The little goalie dads are always saying, "It's not size anymore it's the angles and athleticism..."
They should go look at the D1 rosters and check out the height of the goalies and the leagues they played in. Mostly 6'0" and coming through USHL or NAHL. A handful from the other Jr leagues.
Even the D3 rosters are full of taller goalies although,there are some very good smaller goalies out there too.
