My big issue is how he mentally deals with going from Junior to pro. Not hard to mentally be sound when you have 3-4 years of Junior under your belt. The next step is where things get interesting.
Everyone now become guys that have hard accurate shots and the games become that much faster as well.
Yes, but reflex and positioning and movement are things goalies are expected to improve at the next level. (Who's to say how far. You can't project how much they'll improve with significant accuracy, and that's part of why drafting a goalie is always a big gamble.) Mental fragility, however, is probably the most difficult thing for an athlete to overcome, and being able to stay in the zone and avoid head problems is probably the most crucial part of a goalie's game. So guys who struggle with concentration at the junior level raise some pretty serious red flags about their NHL potential. It's not that they can't overcome that issue, but usually mental stability is part of a goalie's natural disposition, meaning that mental stability is extremely hard to hone for guys who already have head problems, let alone to do so to the level needed to play in the NHL. It's kind of like work ethic or grit: either you got it or you don't. Being mentally fragile can take even the most skilled goalies down to a plebian level. See poor Rinne these last playoffs.
Anyways, Skinner ultimately may not be able to deal with the release of NHL shots, or the speed of the passes, or the mental exhaustion of being
on all the time in the 82-game grind. But at least he doesn't seem to have the critical mental issues that Brossoit had in junior, which have ultimately plagued him so far in his pro career.
(For examples of goalies who had good mental dispositions early that translated well into the NHL, see: John Gibson and Carey Price. I think Carter Hart will be on this list in a few years.)
