Re: goalies, I don't really think it matters who starts. Reimer's Anti-Ottawa Beast Mode seems to usually occur in Ottawa, not the ACC. Not saying he'd lay an egg just cause it's a home game, but there's no particular history here that puts one goalie ahead of another in this case. (except Bernier's recent play in general)
The schedule for the rest of the season is PACKED. And so, even with Bernier as the starter, Reimer should get at least one game before the Olympics. So I think it's a toss up at this point as to who will start this game.
