(Sorry if this was discussed already)
-You DO NOT pull the onside linemen on a Toss to the I-Back, you pull the onside guard, a backside guard, the backside linemen, both guards, OR zone it.
-There should NOT be two or more LBR/ DLinemen going into the backfield against a zone blocking scheme, unless its a blitz.
-You CAN have Load, Lead, and Speed Options in a Flexbone Offense: ask Navy, AFA, and Georgia Southern.
Anyway, I'm still learning how to play since I'm slower to pick up things than most here,
so please don't flame me, lol.
PS: Memo to EA (or if you guys want to check something out), here's some college and pro playbooks that the programmers can make their plays from for NCAA and Madden 2007:
