Use the field goal block on the 1st, 2nd, and 3rd down to stop the opposing in their tracks.
Do not wait too long to make a pass or else it will come up short.
If you are losing the game and have to punt after a touchdown, press Select and do an onside kick. You can even do this at the beginning of the game. However, do not use the onside kick all the time.
Rapidly tap B and it will be harder to tackle you.
