What I find most interesting about this debate is if Dustin Wolf's game will be as dominant at the NHL level due to his size. I think Wolf's resume is the most impressive of the lot, since he's been the most dominant at the AHL level and for longer stretch of games. Hypothetically though, if you were to draft one of Wolf, Wallstedt or Askarov today, would you lean towards Wolf's production at the AHL level or would you side with one of Wallstedt/Askarov who have been good at the AHL level, but also have the prototypical NHL goalie size?
The NHL has been dominated by goalies who are 6'2+ who also have the athleticism to compliment their size. Dustin Wolf's lateral movement is so impressive to watch, there is just no way that he won't be a good goalie at the NHL level but I think it is a very interesting debate to try and project who be more impactful at the NHL level.
Just a quick list of the size of some of the top goalies in the league:
Vasilevski 6'4
Ullmark 6'5
Oettinger 6'5
Sorokin 6'3
Shesterkin 6'1
Saros 5'11
Thompson 6'4
Swayman 6'2
Average Height/Weight of NHL Goalies
It's no secret that playing goalie in the NHL is a big man's game. Wolf seems to be a lock to be Saros 2.0 but I don't think his lack of prototypical NHL size can be ignored.
