I say keep it, you have to. idk about the rest of you, or i guess i shouldnt judge your playing skill, but the turbo is actually appropriate. when running the ball, if you release turbo it gives your blockers time to set up and engage... then if you hit the turbo a step before the hole, it gives you the extra booste that an RB actually strides in real life.
as far a the "risk-reward" when it comes to the turbo button, it IS in a way. When running with tubo pressed, it is actually harder to cut and make turns than it is whithout turbo, if you don't believe me then try it
if turbo is taken out all together, i will not play another ncaa football game.... lol but they wouldnt take it out anyway
