This thing that Allaire is attempting to do with both Reimer and Gustavvson reminds me of another era in Leafs history, when they had a promising young netminder from the then Czechoslovakia, named Jiri Crha, who displayed a butterfly & flopping style, an exciting acrobatics style that suited the Leafs squad well.
Critics claimed that Crha's 'unorthodox' style was flawed and that he flopped too much, so, the Leafs brass set about changing his goaltending style. Instead of improvement, Crha was never quite the same. He was 'ruined'.
I don't like Reimer's too low crouching style. It doesn't appear to suit him properly. It seems that many of the shots go over his head or shoulder side. Also, why does he seem to emit a 'surprised' reaction each time he is scored upon in his crouching position?
Gustavvson perhaps may be a better student of the side-to-side method, since he has a longer reach pad-wise and arm-wise. Still, he too would be better off if he is just himself.
The fact that the Leafs goaltending duo of Reimer and Gus is largely an inexperienced group suggests that it will take time and plenty of patience if we are to see both of them succeed more aptly at the NHL level.
The question now is..can the Leafs afford to wait?
