OL was not good vs Hamilton, but was fine against Toronto. Nichols did not see a lot of heat, had tons of time and was cycling through his reads then dumping off to Harris.
Really issue comes down to Toronto playing quarters coverage and taking away deep shots, Bombers have very little intermediate passing game with lack of trust in Nichols to hit tight windows, throw behinds and other throws that potentially put ball in harms way if slight bit inaccurate. That intermediate passing game is really important in having a balanced offense, if it's not there very easy to defend passing game in general. Bombers have the receivers/backs to do damn near everything, you've got Lawler, Wolitarsky, Matthews who are BIG targets. You've got Whitehead and Demski who bring a lot of speed and YAC potential once they have the ball, you've got Petermann who can do everything but is especially reliable in the middle and also a guy who tends to gain YAC, they had Rasheed Bailey dressed who looks to profile as a thicker Denmark type of steady guy. If a QB can't make the throws to enable this offense to function pretty seamlessly I think that's a tremendous problem in isolation of the rest of the team.
Lapo's excuse for not riding Harris at 20-0 was incredibly faulty and gives some insight into his mindset. Mostly it's just sickening to hear the excuses given what he has to work with. See bluebombers.com.
