Oh hell yeah- Bump and Run- The CB's DEFINATELY need a "jam the WR at the line" setting or some such.... I've been thinking that for awhile now... Even make it an "agility" and possibly "Strength" check at the line to determine if the WR is able to get loose from the CB or some such... would really make this game more realistic !!!
Push Off ability for WR's looks promising as well, as long as there is a counter for CB's all's good!

maybe something like a check during each successfull push off to see if a ref. spotted it ( offensive pass interference).
