during a play where you see your defender about to make a mistake, instead of only having one button to switch to the player with the best chance of making a play a button could be assigned (like L3) to bring up a player selection screen that would assign a button to all the dbs and lbs. so if you saw your safety about to get burned deep you would click the L3 an assigned button would appear over his head, you would click that button and be in control of the safety.
