oilerrocker, you're correct about Lemon being a bit of a scapegoat here. He was 11 for 15 with no INTs and no TDs; whereas Bell was 5 for 16 with FOUR interceptions. Lemon's failing (apart from the lousy receiving corps he had to work with) was yardage (11 completions for 57 yards??). .. but that's on the offensive coordinator, not on Lemon.
I'm not at all upset about Lemon's reaction. . . to be benched in favour of a guy who goes out and throws four interceptions and has a completion percentage way lower, well I'd be royally ticked off as well.
That said, I disagree about 'learning' from Kerry Joseph. Joseph was never a cerebral QB, he got by on sheer athleticism, and that is something that cannot be taught. So if you are a QB like Lemon, you couldn't learn anything from Joseph (whereas you could, say, under Ray or Calvillo), you don't have his physical skill set; Joseph was never known for being a really good reader of defences or anything like that.
You will not be surprised to see someone pick up Lemon? I will be surprised. He's over 30, I don't believe he can 'develop' at this stage in his career, he is what he is, he isn't going to get appreciably better than what he is right now, what you see is what you get, and what you get just isn't good enough in the CFL.
