For all the criticisms of the defence, the D hasn't been our most glaring liability. Lack of offensive production has been the achilles heel. In those fluky wins earlier this year, it was defence and special teams had to chip in and help score points. If you look at it objectively, this team hasn't progressed much beyond last year. We've relied too much on a rookie QB who is essentially an NFL-style pocket passer whose become gun shy from too many hits - and an uncreative offensive scheme that seems unable to adjust. If you want to go to this kind of Calvillo-style, straight drop QB, you have to pass protect and have a decent running game to take pressure off the thrower. We've had neither. Bombers don't have top level offensive experience and collective offensive memory among the coaches, unfortunately, and it shows because they haven't done anything to correct these problems which, as you point out, started 2-3 games in.
I don't think there is any way that you can discount the defence for having lost us games. It's a combination of both. The defence can't stop the run in the 4th quarter of games because they are not schemed to stop the run, and are often tired because they have been on the field too long in some games. Yes that may play into your argument, but it is not the case in all games. To blame the QB and the offensive play calling solely is foolish. Everything has to be looked at in context, and not generally over the period of games, but even each game individually. Your comments certainly do not apply to every game played..e.g. Bombers vs Lions in their first game.
Yes lets blame the QB and play calling solely for all the sloppy tackling on the defence...that will solve everything.
Bombers have been out rushed by their opponent in 13 of their 16 games but have only been out passed by their opponent in 7 of those games.
