Yeah, I ran into serious salary cap problems last season. I overpaid to keep my stars with me. I have young WR, HB, and CB talent. Need to start balancing out the rest of my positions, -especially- my offensive line. I win because of those guys. My entire OL are 94 or higher, hence my running game.
EDIT: One thing I have noticed with drafted players: my defensive players have a much harder time gaining xp than my offensive players. With how much the CPU breaks tackles and how rarely my secondary can actually hold onto the ball for a pick (They catch about 1 out of every 10 that squarely hits their hands), their stats are always subpar. It is almost always my SS or MLB I am usering that actually tackles the CPU ballcarrier, and I only get about 8 picks a season.
