OL, DT's, and LB's are the #1 concerns of this class IMO. These are the guys who tend to get beat up and injured the most because of so much constant contact. Depth at these positions are crucial. You gotta have 10 good OL you can play and rotate on a regular basis to be consistent in this league, and a total group of about 13 - 14 is important IMO. You need at least 6 DT's and 7 LB's you can play at any time too.
