If ever a guy needed to go to the latest developmental league (XFL, USFL, Canada, etc) it is Trey Lance. Other than just sitting him for two seasons to learn in a firm 3rd string role.
The more I read about him, the more I can't believe they gave up so much for him. Something like 300 snaps in 4 years is all he has taken due to c-word, injury, lack of college ball experience, etc..
I remember Irvin talking about him though and said his arm was Brett Favre strong. So talent is there, but mentor with care, if he isn't already destroyed.
