LOL...Me and 2 guys at work were JUST saying the same thing. Why do we need a sprint button? Without it, the game would only be BETTER. IRL, players dont magically get to full speed at will. it takes time and is based on the individual player.
I dont see how it would be so hard just to scrap it altogether. Most sports games nowadays are dropping the "sprint" button, or as i like to call it "TURBO".
