The goalie drafting thing and the height thing intersect:
It seems like everyone, Buffalo included, is trying to find those tall athletic types to play goal. The trend in the NHL has been for the enormous natural physique types and away from worrying about if the guy can just stop the puck. Case in point, there are a couple of draft eligibles who are relatively small by current standards who have both had some solid statistical seasons for their respective CHL teams, namely Everett's Dustin Wolf and Rimouski's Colten Ellis. Both are 6' tall. Both have backstopped very good CHL teams this year and deeply into the playoffs. But... they're not athletics freaks, they're just small guys who stop the puck.
Taylor Gauthier has been good at the U18's, but his WHL numbers are not in the same class as Wolf. Granted, his team isn't either. But he's 6'2" and that seems to be the advantage...
Some of you may remember (or might be trying hard to forget) my infatuation with Veini Vehvilainen, Karpat starter who's heading to NA to play for the Jackets farm team next season. Again, short... but he stops pucks.
I've hoped Saros would supplant Rinne in Nashville for a while since NHL managers are such copycats. If there is a place that the height-ists are rampant, it's in net. Get guys who stop pucks. Worry about how tall they are later.
