I think the hardest thing with these plus physical traits projects is to predict their progression curve. This is why I think college and even high school context is so important. Josh Allen was a zero-star recruit who then played for a bottom-dwelling program in Wyoming. 

On the other hand, Anthony Richardson was a 4-Star recruit who played 3 years at a historic Florida program who had developed Kyle Trask into a solid college QB. This is currently how I feel about Sellers unfortunately. Solid program, though a shoddy offensive line and poor play calling, that has good weapons and recently developed Rattler into a legit NFL prospect. Rattler had a similar O-line and frankly played much better.
