Sorry, I meant
as a team, Blackhawks goalies saw less shots than all but one other NHL team, not necessarily just Crawford. That's my mistake.
2014-15 NHL Summary | Hockey-Reference.com
Scroll over to SA. The Hawks allowed 2127 shots. Less than all but one team, Vancouver, who allowed 1993.
Again, this goes to my statement that the Hawks team defense was instrumental in the performance of the goalies that season. Again, the Hawks were the 2nd best defensive team in the NHL that season, statistically speaking. And from my recollection of their play, that is entirely accurate. Which, again, is why they could ride 4 defensemen through the entirety of the playoffs.
Not sure where you're getting the whole "the 'hawks as a team allowed more shots than 2/3rds of the league in 2015." from. It's wrong. I'm assuming you're using 2015-2016, not 2014-2015. The Cup season is 14-15, not 15-16. And 15-16 is a whole different ballgame. They were bottom 5 in the NHL in SA that season. It was a disgustingly bad team defense that year.
