In past games I looked for Run Block, Speed and Strength. I think this year Acceleration is even more important than in the past. I'm a run first kind of guy and I like having pulling guards or just linemen that can reach the second level on running plays. That's where the speed and acceleration come in.
I haven't gotten past a full recruiting season yet so I can't really speak for this game. I can just say that with the recent NCAA games I prefer to recruit from outside in when recruiting offensive linemen. I don't know for sure about this year's game but historically the tackles transfer well when you drop them down to guard or center. Similarly, guards go up in overall and don't lose awareness when you move them to Center but may drop a point or two if moved out to tackle. Centers move down a point or two when moved to any other position. So for that reason I try to recruit tackles first then guards and only take a center if I can't find a good tackle or guard that is interested in my school. Can anyone say whether my approach still hold true in this year's game?
The theory of bigger linemen helping your running game because your RB can move around him better is interesting. I think I tend to agree because I notice I like running behind a big OL guy then when the defender gets near I shift to one side of the big ugly. The defender then has a good way to go to get around the big ugly. Even if the oline layer doesn't even block the defender it helps me to get separation. Good observation.
