Biggest factor in this one is going to be the Toronto defence. If they come with the same scheme as last week against Edmonton, I'm afraid they're going to be crushed.
Ego Jones rarely allows his front four to pass rush. His concept of bringing pressure is to have the DLine NOT pass rush - - just engage their blockers and blitz his two undersized OLBs, Ball and Issac, hoping that at least one of them will be coming free.
It works if one of the OLBs can be unblocked and get a free shot on the QB. But neither Ball nor Issac have any ability to beat a RB, TE or WR that stays in to block. And that's when everything falls apart for Toronto. It leaves the QB with too much time and more importantly, the secondary can't cover the receivers one on one for so long. Plus, there's no LBs other than Bobby McCune to try and cover the short intermediate routes.
That's why Edmonton kept trying long passes to start the game last week - - to take advantage of the single coverage. Toronto got away with it because Old Yeller Joseph had no accuracy on his deep ball. And other than Fred Stamps, the Edmonton receivers are mediocre. There's no comparison between what Edmonton has at QB/WR and what Montreal has. After Nicholls came in, he took advantage of how wide open it was underneath and moved the ball well on his one drive before getting hurt.
If Montreal leaves Lavoie or their RB in to block, Calvillo is going to have all day to throw and that's a huge problem for Toronto. Calvillo is 100 times better than Old Yeller Joseph and the combination of Richardson & Green is better than anything Edmonton has at receiver. Not to mention Trestman being a bit more clever on offensive play calling than Kavis Reed is.
I'm really worried that Ego Jones has spent all week patting himself on the back for shutting down Edmonton and will come back with the same "successful" game plan against Calvillo and the Als.
