With K.Shanahan coming to Cleveland, Matt Shaub may be a possibility (because of their ties while in Houston). Not saying Shaub is the guy. Kirk Cousins is another name that's being thrown around in Cleveland. I'm sure Cleveland wouldn't mind trading away one of those high round picks to get cousins.
Obviously the piece they are missing is a crucial one...and often times the hardest to obtain. Heck, we spent 25 years after bradshaw trying to find his replacement.
I think the browns could be real good IF they find a franchise QB.
1-Darqueze Dennard CB Michigan State
2-Jordan Matthews WR Vanderbilt
3-Jordan Tripp ILB/OLB Montana
4-Christian Jones ILB Florida State
5-Brent Urban DE Virginia
5-Michael Schofield OG/OT Michigan
6-Kadeem Edwards OG Tennessee State
6-Ben Gardner DE Stanford
7-Aaron Colvin CB Oklahoma
Manziel may have a very high ceiling, but putting him "Much higher" than Wilson may be a stretch. From what I have seen, Wilson can do it all.
