Well, I'm just thinking realistically..... the staff already has Tim Burns, they like Tavarish Dawson and dont mind locking him up early and I dont believe the staff is gonna take 3 5'10 CBs. Out the the, 3 Knowles is the most physical and Versatile.
The Safety class is very strong, besides the obvious studs the guy just mentioned, there are guys like alfonzo Allen, Jantzen Dunn, and I personally think Kevin Knowles good be an outstanding FS with his range and physicality.
