Correct me if I am wrong but every body seemed to have forgotten that a CFL coach cannot challenge any ruling in the last 3 minutes of the second half. The referees were actually treating Taffe as if he had an option to challenge. I'm sure that the initial challenge on the touchdown came from the officials upstairs. But when Taffe challenged the ball possession call the referee simply said that it was not a challengeable result. Are the rules different this year?
On the topic of coaches challenging plays I beleive they must start penalizing coaches for tossing the flag to challenge calls as a means of protest even when they know it is not challengable. It slows down the game and quite frankly the coaches stomping around and throwing the flag on the ground look rather childish. Delay of the game penalties should be dished out because they should be aware to the rules.
