Maybe it's just me, but I sometimes wonder how my starters would fare against my backups or how specific players on my team would compare to other guys at their position. It would be interesting to have an option once per season (maybe the first scrimmage of the season?) to just play an intrasquad scrimmage, where the results could be helpful in figuring out the depth chart for the season.
(Or maybe I've just been watching too many college basketball pre-season intrasquad scrimmages....)
