One of the best ways to block a FG(Might be a glitch not sure though)
3-4: Normal: Renegade
Setup:
Shift D-Line to the left(When Looking at the screen) and RB + RS Down
Shift LB's to the right(When Looking at the screen) and RB + RS Down
Control a Safety and don't get involved in the play let the CPU block the kick, Don't move any of the LB's or Linemen.
This works a pretty good amount of the time but, I think should not be allowed in MS Games just for use against Ranked Opponents on XBL.
Thank You, Let me know how you guys like it or if it's not working i'll try to explain it better...
