Option pursuit ,ect

I'm so irritated with the option pursuit on this game. Even when you tell the defense to focused on the pitch guy, they run right to the line and get stuck in stupid animations. Also i get the home field advantage stuff...but we should still be able to audible after 3 times... not realistic considering the computer does it with no issue... one last thing can we please have .ore than 16 teams for teambuilder... 20 would be perfect....
