My point was that a lack of data was the problem. I don't think, when two are said to be nearly even, that you don't give both a shot on the field.
I think the fact we saw Clifford throw the ball more in his limited action compared to Stevens snaps over 3 seasons means something. Sure, without Franklin coming forth and saying such, we'll never definitively know, but why such hesitation to get Stevens any meaningful snaps?
My take: Stevens is a decisively lesser passer than Trace; the initial competition was not as close as the media was led to believe; the play calling with Stevens in vs Clifford in had different tones (RPO and zone reads vs throwing down the field).
Go back to the Michigan game. Trace was a one legged man. Stevens got the nod and rushed right into an INT. Trace returned until the game was well out of hand before giving way to Stevens late.
