Here are facts:
1. Lance will be third string QB, so this requires we carry 3 QBs. It will cost Dallas a roster spot elsewhere (Most expected us to carry just two QB on 53)
2. It'll be extremely difficult for Trey to get practice reps at all for the 2023 season. Camp prep is about over. And since he can't go on practice squad he'll have little chance to develop aside from just learning the offense. (3rd string guys get virtually no reps in-season)
3. Lance has been insanely raw since he was drafted and hasn't advanced far. Does have unique raw physical ingredients.
4. In addition to the 4th round pick Dallas will lose $2-3 million AAV that could have gone towards extending Micah, Steele, Lamb.
Opinion:
It's wildcatting. A wild gamble but with potentially big return.
