In Guelph tomorrow, the high is 7 and the low is 0 and the precipitation forecast is rain. So cold rain, but not really cold rain (or freezing rain). Some pundits have predicted cold weather would benefit Montreal because I suppose of Hamilton's poor running game versus their strong passing game. However Henry Burris having played in Calgary for years has significantly more cold weather experience than Troy Smith (who played at Ohio State University and not much at all in the NFL). Smith's completion percentage so far in the CFL has not been anything to write home about and I can't imagine cold rain will improve on it.
In terms of the running game, if the Cats decide to run, they may go with Jerimiah Masoli at quarterback and run the wildcat again which worked against Montreal in the last game.
