Nah this doesn't make any sense. That would be like saying any player in the OHL Leaf fans are experts on. I very much doubt any significant portion of fans were repeated viewers of college hockey.
How many power forward top 6 wingers are in the league today? Under 10? Goalies also simply do not have the value of other players. We have tons of history to show that. Nevermind unproven prospects.
That's fine, I don't begrudge anyone their opinion they rather have Knies.
I was mostly responding the the portion of your post that said
"If it wasn't for the hype, no one is saying Wallstedt is any good for a .910sv% in the AHL "
A .910 and winning record with the team that was in front of him is ridiculous performance for him, and well worth the Hype.
As far as knowing any player OHL wide, it's not the same thing. There are 6 D1 hockey teams in Minnesota, but it's the U of M and everyone else. Everyone else will have some small regional support from current students/alums/locals, and with the exception of the brand new St Thomas are only D1 in hockey.
U of M support is more state wide, average 9000+ in attendance, and has almost all games broadcast on TV within the state. None of the other programs have that. If you're a hockey fan without a direct tie to the other colleges via location/attendance, you probably grew up a Gopher fan.
