Guys, we've had this issue come up in a various games and OD's. The following comes from the TSO Gameplay Guidlines. D.4.0 - Defensive Subs: OLB are not suppose to play DE, Safeties are not suppose to play LB, etc in any package or formation, even if it's a game based package. It is just too much of an AI headache. Keep players in their original positions at all times. Though they are general guidelines, this is a set rule in SoCom.
