NFL Blitz

as their is no longer an online community for this game you will need to boost. you need two people. you basically create a blitz team and for co-host put as guest. sign in a second controller for as the guest on your team. then both search and start the game. at kickoff let it run until the playbook pops up then have the guy not going for wins quit out. you will get about 4200 points a game. once you get the cheevo for regional or if you still need the national then switch and do the same for the other person.

it might go faster depending on what region(state) you choose. New Mexico went faster for me than the guy i was boosting with.
