It's been an interesting topic before the season began, and even after the win. Here's how I saw things in the first game:
1. Denard is fast
2. Denard has some nice cuts
3. Denard's arm, while strong, looked like that of a HS QB that completed 45% of his passes
4. It didn't take long for the WMU defense to figure out how to stack the line against him to mitigate 1 and 2.
First game excitement certainly played a part in his hard, erratic passes and some of the more tentative decisions. Overall, he played well, and the broken play was explosive. But, the playbook was maybe 15% of what seemed opened up with Tate. The result: one play versus a couple dozen. I really think that the game made the QB situation much clearer than "1a, 1b and 2". There is a clear 1, 2 and 3, as I saw the game unfold.
I'm not dissecting the game, but trying to think more towards the future. This might be controversial, but I don't see DRob being the starting QB without some kind of (please, no) injury. But, he does need to be on the field more than a few snaps. At QB, this will be even less likely when one Devin G. arrives next year. Make no mistake, DG is the future, and he and Tate will push each other hard.
My point: I think that Denard's QB time should come to an end as this season winds down. We need him as a capable backup for this season, but he also needs to learn a position that can get him on the field as a playmaker on every down. I saw several people suggest RB, but he doesn't have the frame for that (blocking? trucking?), but I think he seems better suited for the slot or out wide. He can make corners have nightmares, and heaven help any linebacker that ends up with his assignment. I could see him very much in a Percy Harvin-ish scheme.
