Miracurl on Ice

At the risk this phrase may have become part of the sports vernacular by the time I write this, cudos to @PeteJolicoeur who first coined “Miracurl” on twitter after USA defeated Canada in the Semifinals of the 2018 PyeongChang Olympic Winter Games.  Careful not to Google it or you will find that MiraCurl is in fact a Professional Curl Machine that will leave your hair with an 80’s perm your preteen self may have always wanted.  With digital marketing what it is, you may also receive shampoo adds on your smartphone for the next 6 months.

Even if you are not a hockey fan, the Miracle on Ice from Lake Placid in 1980 is a seminal moment, with USA shocking the world by defeating the Soviet Union and ultimately taking the Gold medal.  You could make an argument that hockey leapt from obscurity in the American sports scene to take a stronghold as one of the big four (kinda?).  Perhaps curling will take a leap from its position of punchlines in a stand-up routine to a legitimate sport only mocked in affection.

Even if the John Shuster rink (yes, curlers call teams a “rink”) loses to the Swedish swashbuckler Niklas Edin, the win against Canada's Kevin Koe and Silver medal for USA could help curling grow even further south of the 49th parallel.  Perhaps more Americans will join Mr T, The Boss, George Clooney, Homer, and countless others, and get hooked on the game each winter rather than just every 4 years.

With all due respect to mini-Herb Brooks, the comparisons of Team Shuster to the 1980 USA Hockey team is an unfair comparison.  That USA hockey team had no chance.  If I were allowed to gamble at 8 years old someone named Vinny or Rocco would still be looking for me.  John Shuster is battle tested, having appeared in 7 World Championships and 4 Olympics, including a bronze at the 2016 Worlds.  The knock on this team has been their many International appearances without reaching the summit, but I had them as dark horses heading into this event.  The key final draw (yes, curlers call a series of games a "draw") against Great Britain was an example of how they could draw (different definition here) on that experience to execute at the biggest moment while minimizing any strategic errors or mental mistakes.  From the vantage point on my couch, the Kyle Smith squad is talented, but lacked the composure that comes from having been in the moment before.  Shuster is deserving  of their medal and have earned it, not just this week but from years of preparation.

If you haven’t seen this blog before, think of it as Curling meets Bill James or Moneyball-Curling.  There were several interesting scenarios in the semifinal game, let’s examine a few of them:

First End:  0-0 - CAN has Hammer
Nothing really to discuss here.  Most of the week we saw teams go at each other right away but with the emotion running high in what is the most difficult game to play (a win guarantees a medal, a loss does not), not a bad choice by both teams to run them up the sheet and end up with a blank end. 

Second End: 0-0  - CAN has Hammer
Canada third Marc Kennedy, perhaps the greatest double peel thrower in history, misses both of his attempts and in fact jams on his last shot to leave USA sitting two…

 Canada is Red
Shuster chooses to hit and roll off the Canada stone at 9 o’clock.  As Canadian broadcaster (and 1998 Silver medalist) Mike Harris telestrates, it’s a conservative call.  They have Canada on the ropes and might be better drawing to sit three and block the path to the button.   

I understand their concern.  With Kevin Koe you are always worried about leaving a big shot for 3 or more points and John is being cautious to limit Canada to no worse than 2. However, he may in fact be increasing the odds Kevin gets two.  Kevin Koe up two with 8 ends remaining is 30-5 (86%) since 2010.  I’m in Mike’s camp here and would have liked USA to bring the pressure, even if it introduces a risk of three points.  When you are the underdog, it’s important to take chances and this is a great opportunity that may not come later.  Even as the favorite, I expect Kevin would have played the draw in this situation.  USA is fortunate that Koe’s draw was heavy and Canada settles for only one point. 

Third End: 1-0 CAN – USA has Hammer
With three rocks remaining, Canada sits three and you might suspect they have no worries. 


But this demonstrates how a corner guard can create points for the team with hammer.  A fantastic roll by John on his first forces Kevin to play a soft tap.  The USA stone jams, sitting second and USA could have had scored a deuce if John’s final shot had curled an inch (2.54 cm) more.  It’s 1-1 after 3 ends.

Fourth End: 1-1 – CAN with Hammer
Two runbacks by Canada second Brent Laing don’t go as planned (as do the next two attempts by Kennedy) and USA has the Canucks chasing.  On John’s final shot, rather than place a guard and allow Kevin to draw full four foot for a single (likely >95% for him by this stage), USA smartly places their rock on the side of the four foot, leaving a delicate hit. 


No mistake and Kevin makes his final shot look easy, but it was more difficult than it appeared, especially knowing the score goes up afterwards.  A steal here would have dropped their Win Probability (WP) from 58.5% to 41.5%.

Fifth End: 2-1 CAN.  USA with Hammer
An interesting strategy by Canada to place two centre guards nearly backfires as USA seems poised to score a bunch.   

This is a very unorthodox call by Koe. The double centre guard is a very aggressive play that is most often used when tied or down without hammer and often not this early in the game.  Because USA had placed a corner guard, Kevin knew they wouldn’t be facing two rocks in the four foot.  The ploy is likely an attempt to get many rocks in play and put USA in a less comfortable position, but it’s Canada who gets into trouble.  I’m not enamored with the call as one of Team Koe’s strengths (usually, perhaps not this game) is the run back, and by placing two guards they are making these more difficult.  It appeared to be an unnecessary risk without hammer and something uncharacteristic from this squad.  A decision John may second guess is playing out to the wings by third Tyler George.   

Rather than be tempted to play on it, Kevin and Marc decide it’s now or never and draw behind centre, forcing play back to the middle and ultimately holding USA to a single.  As Canada lead Ben Hebert says, it felt like taking three points to escape that end.  On John’s final stone, USA does take some of that underdog risk, attempting a long runback for 4 points.

From my vantage (at home, on my couch) and based on the result, it didn’t look makeable and seemed more likely to produce a steal (perhaps of 2 or 3) rather than the mit full they hoped for.  Even the USA bench looks skeptical. 

 Um, yah, ah, um....

Great line by John as he and Tyler study the shot however, “the physics just doesn’t allow it”. 

Sixth End: 2-2. CAN with Hammer
Flip side of the hazards seen the previous end. Canada fails to place their corner guard in the Free Guard Zone, allowing USA to hit and sit two.  It’s a conservative call and perhaps if their first stone had been above the four foot rather than behind the tee-line, they may have thrown a centre guard.   

The result, Canada has no chance for a multiple score and is chasing just to blank.  USA kills an end, shrinking the game down to 4 ends.

Seventh End: 2-2 CAN.  CAN with Hammer
Two half-shots by Brent and Marc lead to another blank end.  Koe is not concerned however, they are tied with 3 ends remaining.  USA has been conservative without hammer the last 2 ends and shortened the game, but time is running out.  The average WP at this stage for team with hammer is 64.4%.  As you might suspect for Koe in this position, it's higher than average (44-18 or 71% since 2010).

Eighth End: 2-2 CAN.  CAN with Hammer
On skip’s first, John could hit to sit two but chooses to draw behind centre instead…

 Baby blue and grey with a red hat. Priceless
A deuce for Canada (USA WP=14%) is only 9% better than a three (WP=5%) so the strategy is to create a force or steal, even at the risk of a big end for your opponent.  I like the call because Kevin would either be left with a double to sit two, a hit and roll to sit first and third buried (often pronounced “berried”), or have the opportunity to draw top button, leaving a difficult shot for USA and a likely deuce.  Better for John to attempt to make the draw first, but...don’t be heavy (he is).  Kevin has a great chance to score here but instead rubs the rock in the top twelve.  A great roll by John and Kevin, going wider with a different path, surprisingly comes well short with his attempt and an unlikely steal of two puts Canada behind with two ends to go.

Ninth End: 4-2 USA.  CAN with Hammer
It appears to be another blank end until Shuster’s last shot.  Rather than hitting the Canada stone in the back four foot, John chooses to try a freeze and force Canada to a single.   
Tyler tapping for the freeze

I dislike this call, and luckily for USA, Kevin misses a makeable shot for two and is forced to a single.  I understand what John is thinking.  At worst, surrender two and have final stone in the last end (WP=79% for top teams, 75% average). The problem I see, in most cases he will either leave a blank anyway, or a shot for two points (which he did).  Leave the blank and USA is up two points in the final end, WP = 89%.  If Kevin takes one (which was the result) USA’s WP only increase 1% to 90%!  The outcome USA took a risk (10%) to achieve, only netted them a 1% advantage.  Teams in the past in Koe’s situation (two down in the 9th end) have sometimes intentionally taken a single point. Kevin Martin did this in 2007 against Blake MacDonald to win the Alberta finals and qualify for the Brier (Canadian Championship).  Blake was actually the fourth for that team (threw the final stones). The skip was Kevin Koe.

Tenth End: 4-3 USA. USA with Hammer
The moment where lead stones mean everything.  John Landsteiner of USA makes both his tick shots and Canada is left with nothing covering the four foot.  Koe smartly attempts to set-up a double roll towards centre using two staggered corner guards.  

The idea is to have the shooter roll to a centre guard and the impacted stone spins off the other corner guard and rolls into the centre of the rings.   
A low percentage play but at this stage it is their best chance to extend the contest.  Mike Harris mentions that Ryan Fry (2014 Olympic Champion) threw a similar shot at the Brier a few years ago.  Kevin is unable to make the miracle shot and ultimately John Shuster is left with a nose hit for one point and a trip to the Gold medal game.

Canada clearly had an off game but Team Shuster were ready for the moment.  They were able to keep it close (despite starting without hammer), and eventually capitalize in the right situations.  Koe failed to score more than a single in the game, something that had not happened the entire event. 

USA started 2-4 and have won four in a row, against the two tie breaker teams (Great Britain and Switzerland) and twice against the three-time Canadian and two-time World Champion.   

Raise a glass to the lads from Duluth, MN (and one from McFarland, WI)…and then on to Swedes.
