If we consistently saw the Howard that we saw last night, we don't need AJ (though I still think he'd be valuable to bring in for certain packages/situations). Obviously, that didn't happen at all vs. OSU and has been sporadic in other games. For the most part, Will took what was available last night and didn't force stuff. If he can do that most of the time, we're good.
I do think the alternating possessions will go at some point - either because Howard fully settles down or a legit defense stuffs it - but I imagine it's actually mentally beneficial for both because they know exactly what the dealio is and can mentally prepare - as opposed to someone getting yanked, not knowing if/when they'll go back in, etc.
As weird as it sounds, there's a degree of certainty to this concept and it's working (for now).
