I just found this game not to long ago and am now addicted to it. If you havent seen it you should check it out.
Goal Line Blitz is a browser-based multiplayer online game based on
American Football. You can create players, level them up, and
participate in a team’s attempt to win the championship. You can also
gain control of a team and set tactics, recuit players, build your
stadium, and more. This is a truly community-based game. You should get
to know some of the users on our forum. Most would be happy to answer
your questions or recruit you to their team.
