What I do in NCAA 14 and the last Madden I had was I always limited myself to only moving like the CPU could. If I wanted to, regardless of the level, you could get some juke chains down and practically get 10+ yards a carry. The quick left, right step always guarantees you to shake whoever is within 5 yards of you.
Hopefully with RPM gone are the days of the ball carrier having a huge advantage of defenders in terms of movement which creates wide open gameplay. Also, if it isn't fixed by now, hopefully AI backs will soon actually use the same moves we can use and they don't run so static every play.
