Excellent question
Tennessee was in the same position once upon a time. Backup made plays only to be benched quickly.
Mom and Dad pressuring Norvell?
I dont think Glenn is the answer and Norvell doesnt have another choice. My son graduated high school same year as Glenn and they played them (Laussane) twice.
Much like Ty Simpson, I didnt see it as an immediate high P5 guy.
He's probably going to need 2 years to get used to speed at this level and this is 2nd year with very limited reps in first-year due to injury and Travis...
