# The Long Odds of Canada’s Long Stanley Cup Drought, 2019 Edition

**April 2019**

I thought I should update this blog, as two
more years have passed since the last time I looked at this phenomenon. The statistics on Canada’s long run of years
without a Canadian team winning the Stanley Cup have only gotten worse. There have now been 24 straight years without
a cup – should this year prove dry as well, that will be 25. That would be the Silver Anniversary of not
winning the esteemed, and partly silver cup.

The original bowl
was made of silver and is 18.5 centimetres (7.28 inches) high and 29
centimetres (11.42 inches) wide. The current Stanley Cup is topped with a copy
of the original bowl, made of a silver and nickel alloy. (Wiki entry)

At least this year 3 Canadian teams made the
playoffs (about what one would expect from probability theory) – the last time
I looked at the drought (2016), there were no Canadian teams at all.

So, the updated question is “what are the
odds of no Canadian team winning the cup for 24 straight years?”. It turns out, that’s a very low probability
event, about .0033 in usual probability terms, or 0.33%, when expressed as a
percentage. In other words, about 1
chance in 300.

One way to calculate that is via the binomial
theorem. You can look that up in a table
(lots of them can be found on the internet, or you can find one in a stats
textbook), or use the excel function BINOM.DIST. The calculation can be described as “how many
times would you get 0 successes in 24 trials, assuming the probability of success
in any given trial was about 7/31 (actually, I used .212 instead, to reflect
the changing percentage of Canadian teams in the league over the 22 years).

It is also interesting to see how the odds of
the losing streak change, as the streak grows longer. I calculated those odds for streaks from 1 to
25 years, and graphed the results, as shown.

As you can see, the odds of this have been
quite low for a long while.

Another way to look at this, is to calculate
how much money you would win on a bet like this, as the streak increased. The accompanying graph shows that, if you had
walked into a betting shop and made that bet in 1994 for $100, you would now be
on track to pick up nearly $40,000. Obviously,
betting that a losing streak would last for two decades or more, is a pretty
slow way to make money, but in illustrates just how unlikely such a long losing
streak really is.

You can also set up a Monte Carlo for problem,
as a check on the binomial theorem result.
The procedure is:

·
Make a
list of 30 teams, and fill with random numbers (use rand()). That will represent 1 season of play

·
Make 7
of those Canadian teams, via assigning a 0/1 variable, with Canadian=1.

·
Assume
that the team with the highest random number won the Cup that season. Do this by finding the maximum randomly
assigned number (use ax(list)).

·
Assign
a 1 in another column to the team that has the maximum value (use if(team=max_random,
1, 0) .

·
Multiply
this column by the Canadian/NonCandian column, and put the result in a new
column. If the winner is a Canadian
team, that column will total to 1, otherwise it is 0.

·
Now,
you have determined whether the Monte Carlo has a Canadian team winning the Cup
in Season 1.

·
Repeat
that 23 more times, to simulate 24 straight seasons.

·
Calculate
the sum of the Canadian winners over the 24 simulated seasons.

·
Test
to see how often that comes up to 0.

When I did this, I found only 1 occasion in
my 24 season streak tests, out of 1000 trials, where no Canadian team won the
cup during that stretch. That’s somewhat
less than what the Binomial Theorem estimate gave, but with such small
probabilities, it can take a lot of runs for a Monte Carlo and a closed form
solution to converge. Still, the results
are pretty close, and both demonstrate just how unlikely this finding is, on
statistical grounds.

Note that most likely result, based on the Monte
Carlo, is between 4 and 7 Canadian team wins during a 24 year stretch. That makes sense, as it corresponds to the
percentage of teams in the league that are Canadian based.

So, we have awfully long stretch of losses occurring. It strains credulity to consider this to be merely
bad luck. Some other theories have been
propounded:

·
It’s
related to the Canadian dollar. But that
doesn’t work, as the Canadian dollar has varied considerably during this time
period, sometimes being lower and sometimes higher than the U.S. dollar.

·
Another
theory states that hockey players can’t stand the pressure of playing in the
Canadian cities, where the sport is taken very seriously by the fans.
Therefore, the players choke, basically.
That theory seems unlikely – after all, professional athletes have come through
a grueling system of training and preparation to make it to the big
leagues. They know how to handle stress.

So, the only theories remaining (that I can
think of), are:

·
It’s a
conspiracy - the league helps the U.S. teams win (say, via referee decisions or
Board of Governor actions), to help out teams in the more financially uncertain
U.S. marketplaces. But, that seems like a
difficult to conspiracy to actually make work, as the league simply doesn’t
have that sort of control over the referees or the owners.

·
Economics
- Canadian teams can make as much money
losing as they can winning, so they don’t manage their business affairs with
winning as a significant priority.
Indeed, playing rope-a-dope with Canadian fans might be an optimum
strategy, keeping player payrolls relatively low, while holding out “wait until
next year” hopes for the hockey-mad fans, who will show up, come what may.

Perhaps the Canadian sports media will give
another go at this. In recent years they
have nodded towards the strange phenomenon each spring, almost as a ritual
now. Their explanations are usually
pretty lame, and they also reveal their weakness with statistical reasoning during
these efforts. Not that I expect much
from a journalist, when it comes to math.

At any rate, the Great Canadian Stanley Cup
Drought is truly a conundrum.

========================================================

If you have some spare time, possibly due to
lack of interest in the NHL playoffs, you might want to consider a nice road
trip, exploring the non-hockey contrasts between Canada and the U.S.. If so, then “On the Road with Bronco Billy”
is definitely your book.

Sit back and go on a ten day trucking trip in
a big rig, through western North America, from Alberta to Texas, and back
again. Explore the countryside, learn
some trucking lingo, and observe the shifting cultural norms across this great
continent. There's even some hockey playoff talk (Oilers-Denver and
Oilers-Dallas), for those nostalgic for Canadian playoff representation.
