I kind of like Egnew more than Charles honestly. Mizzou has been good to us in recent years!
So I guess that leaves Boykins. He'd replace Weems pretty well on ST. Honestly, neither has done much to improve their draft stock (Charles with the DUI, Boykins with the leg injury). I'd rather us take a project WR in the later rounds that can return like Devon Wylie. I really like Trumaine Johnson since he fits the big nickel package that Mike Nolan likes.
so my ideal mock draft would probably be something like
2. Brandon Thompson DT Clemson
3. Trumaine Johnson CB/S Montana
5. Michael Egnew TE Missouri
6. Andrew Datko OT Florida State
7. Marquis Maze WR/KR/PR Alabama
7. Derek Dennis OG Temple
