How to get faster for football?!
Practice, practice, practice. Watch youtube videos on how to run... and pay attention. Then practice more.
That really depends. Faster in endurance running or short-distance?
foot fires and doing the latter on the ground made me faster. I played football and was a wide reciever. I got faster when my agility was better and I just started to run a lot. Always think "light" and stay on your toes.
