Substitutions, quickest and simplest way to sub for WII version?

[uscfootball]

when in the Play Now Mode, if you choose a team but want a player to be the starter, whats the quickest/simplest way to do this without having to choose all the possible plays that the player can be on the field.

example, I choose the Saints, but Deuce Mcallister is the default starting HB. I want to replace him with Reggie Bush for all running plays.

Whats the quickest/simplest way to do this, or is there a way?
