100% agree. I hope it's just Groce experimenting to see how his young guys handle crunchtime before we get to the important part of the season. It will be a shame if he didn't learn his lesson from last year.
I don't pay enough attention to the rotations on a day-to-day-to-week-to-season-to-etc basis, but I've heard greater basketball minds than I(not hard to do) say that Groce's rotations are actually pretty crazy until conference play kicks in. Then a more 'normal' rotation is put out for conference play. Perhaps those that pay attention can confirm or deny what I've been told (but not noticed).
