Ok, Here we go.
First my suggestion is to swich you Punt/Kick Returner to the fastest man on your team.(Trust me on this) You want to take the ball to the side lines so If you do fumble it will go O/B. Next you want to hit stick AMAP speed boosting isn't going to work here unless you break free.
With running, I perfer a power back over one with alot of finess. This allows you to concentrate on running it up the "gut" which, if I'm right, is the fastest way to the endzone. Hope I helped!
