This again...
Here is my post from the general discussion thread regarding this topic.
I suppose it's time to see if Jake Allen can win a competition for number one goalie.
It is not.
Each year there are maybe 1-2 goalies who don't experience the type of slump Binner is in. Those guys are nominated for the Vezina, along with 1-2 guys who had a slump like this (or bigger) but also had runs of insanely hot play. This is being a starter in the NHL. Binner still has a .912, a 60% quality start rate, and a +3.85 GSAA.
Diving into advanced stats, let's filter out goalies with less than 900 minutes played at 5 on 5 to get our sample of the 40 goalies in the NHL with the most TOI. At 5 on 5, he has the 13th lowest
expected SV% (which measures the quality of shots faced, not goalie's performance) and has faced the 11th most shots in the league. He is facing a difficult workload. The difference between his actual SV% and expected SV% is 12th. His 5 on 5 GSAA is 12th. He is 6th in high danger SV%, 9th in medium danger SV% and 20th in low danger SV%. You'd like that last number to come up a bit, but the difference between 10th and 20th in that stat is just .32% (98.03% to 97.71%). At the end of the day average to above average goalies are stopping low danger shots at roughly the same rate. We are probably talking about 1 extra low danger goal than the top 10 goalies at this point in the season. As that is the only non-above-average stat, that's not even remotely troubling.
Binner has had a soft few starts, but he is undoubtedly the starter. There is not a competition for the number 1 job here.
Jake deserves a shot to push him for more starts.
Jake has absolutely earned more starts. Binner had a really high workload in the first 3+ months of the season and is currently tied for 5th in starts. Given Allen's play, we should be deploying him like a top tier backup unless/until his play drops off. Halak has 22 starts this year. Khudobin has 17 starts this year. Both of them have outplayed their starter at times this year and both of them will undoubtedly be wearing baseball caps throughout the playoffs barring an injury. They are squarely backup goalies, but they play more games than your run of the mill backup. Allen deserves that role (and at 14 starts this year is on the cusp of it).
Allen has earned an extra game every couple weeks over the remainder of the season and there would be absolutely nothing wrong with giving him 60% or more of the starts over the next couple weeks if he stays hot and Binner doesn't. But that is not a goalie competition. That is riding the hot hand, which most teams do at some point in the year even when they are 100% confident about who plays game 1 of the first round.
