DTR is a developmental quarterback.
Developmental QB's develop. DTR is not developing.
The team needs to see what he can do. One way or the other.
And they did just as we all did.
Is there promise? Could he be a backup? Should he not be part of plans for the future?
No, no and no are the answer to those questions and we all saw it first hand.
It wasn't bad coaching decision to let him play. It will be bad decision by this FO if he is back on the roster next season.
