With all of that said, why the fuck did they start Trotter in the first place?
I
think (and this is merely a theory), they were neck and neck in practices and scrimmages, and Trotter got the edge due to Seniority.
However players, especially QBs do not always perform the same at practices & scrimmages as the do in real game situations. I believe (and hope) that Trotter is just one of those guys that can't handle actual gametime pressure, and performs much worse in actual games. Mosely, however, (again, I hope) handles this pressure much better. At least it appears that way from his few snaps he's taken.
