I saw two upper days in a row that had some type of military press. I know Westside hardly does any, and Louie stated that the ones that do a lot of them, didn't see any benefit.
So given the premise that you're always doing speed work benching, then another maximal press on ME bench day, adding in even more overhead presses just increases the amount of work your anterior delts endure.
But if he's only rotating them once every so often, probably not a big deal. It's hard to tell because I cannot tell what the hell he's doing in here half the time!
