Proven? Nope. But they had their own style. Now it seems as though Allaire tries to turn them into the same person.
We have no idea what he does with the goalies though so I dont see how it's fair to blame him. He certainly didn't ruin Hiller and Giguere when he worked with them. Also, Reimer is still young for a starting goalie so he could easily bounce back next year. I just find it highly unlikely that all these goalies would sign with us to work with Allaire if he's such a bad goalie coach like some are saying.
