re: Will Canada allow a legitimate quarterback competition?

I think the coaches more than likely enjoy making 7-figure salaries. It stands to reason that they'd play whoever gives the team the best chance of winning, given that winning is what will ultimately keep the $$$ rolling in and/or create even better opportunities for them.

Whoever the starting quarterback is come September will be the guy who at that point in time, is the best at his position on the team.

There may be guys behind him with more potential, but until such time as those guys playing make the team more likely to win they'll have to wait their turn.
