I wasn't there but from what I heard some tidbits:
The RB's are going to be just fine. McCaster and Alessi will carry the bulk. Mix in some McNutt and Christian Turner, the freshman who the coaches love.
Offensive line from what I hear is set barring injury with Spencer, Wiggins, Hy, Sharp, Fraser.
Reed, the florida transfer is still running with the 2's as of now trying to get used to the system. Our DT's and LB's are stacked. D-Line as a whole, especially in the middle is pretty deep and talented. There is competition to see who the starting corner's will be. Larkin, Smalls, Hall, Thomas. That's the biggest area of concern.
