This is exactly why Montez should come out a year early if he has a 1-2 round draft grade. He has a better chance to get with a better team than getting a top 5 grade next year and ending up with the Browns.
At the end of the day it's all a gamble. If you wait too long you may end up like Matt Barkley, who was touted as an early first round pick before he went back to USC for another year and shredded his draft stock there. Barkley is now on his sixth team.
I just feel like Montez needs work and things will have to align for him in a certain way, more than they may have to for others, if he wants to establish himself as a legit NFL starter, which he has the athletic potential to do. How far he'll go is all down to the mental things as athletically the sky's the limit.
