I find our whole discussion on our goalies as nitpicking. Reimer gets nitpicked because while getting results, he isn't doing it prettily enough. Bernier gets nitpicked on because while being consistently good, his team-based stats are not as good and he has let in a few really flukey goals.
That Bernier is worse later in the game is an area he can improve on, not a problem. It would be a part of the problem if it meant he wasn't putting up good numbers, and therefore becoming a weakness and not a strength for the team.
I don't know why, but Leafs fans seem incredibly picky with their goaltenders. Completely perfect snipes is somehow bad goals, letting in fluky goals is unacceptable even though even Lundqvist and Rask has done so this season. So many lose sight on that the overall impact of our goaltenders are tremendous, no matter who is in net.
The only real worry, as opposed to just areas I think they can still improve in, I have about our goaltender is that Reimer seems to start swimming around when things are not going his way. I find that a much larger problem than his rebounds.
