Oh, I know. When I was at Ferris, Craig Lisko set the program's all time career save percentage mark with .893. Needless to say, that record has been blown away a few times. since. In the early-to-mid 90's, the benchmark was around .900 in the CCHA, with a GAA under 3.00. If you were above .910, you were elite. Darren Madeley and Steve Shields immediately come to mind. And then Blaine Lacher played LSSU into the NCAA title game in 92-93 with an .892, until they ran into that insane Maine team.
EDIT: Going back to the goaltender in question, Henry Dill was dead last in Hockey East in save percentage his freshman year, by a full 25 points (.894 vs .869). It wasn't even close. He was dead last in the conference in GAA by nearly half a goal per game. He didn't rank at all in his sophomore year, due to not having enough minutes to qualify. He played in 7 games for a team that went 8-24-4.
Look. I don't know the kid. I have no beef with him. If I met him, I'd happily buy him a beer. I hope it turns out that the kid does well. But at the same time, I wouldn't go getting my hopes up, either.
