I love that you claim to attempting to be objective (or, non-emotional, at the very least ... maybe I can grant you that).
The problem is that you're misapplying data to draw inferences.
It's almost like you don't recognize that I'm a quant.
How is it that you're misapplying data? Well ... you're looking at a guy who was still rehabbing during the spring ... so he didn't do much more than work on 7-7 stuff during that period.
Then, when he'd see some of the most formative experience with our O during fall camp ... he missing a substantial portion of those practices with his tweaked muscle from the open scrimmage.
Thus, you're trying to claim that Iowa "broke" him ... when you're talking about a QB who last saw saw action nearly a year ago. Then, on top of that rust ... you're looking at a guy who has missed a lot of important time drilling in the O so that it could efffectively become more automatic for him.
If you wanted to have a better "control" on your data ... in order to allow for more of an apples-to-apples comparison ... it would have required him to have been healthy and been a full-go for each of the camps. That way we'd be able to draw better comparisons to his performance at Michigan vs Iowa.
Of course, as others have indicated ... there still is the issue of how things work with the different talent-level surrounding him at Iowa vs Michigan.
