To the OP, I'd have to agree. We had this same discussion on the Celtics Beat podcast that ran on Sunday. Host Rich Conte set the over-under on players on the current roster that would still be here for next year at TWO, and he chose the under. I wasn't quite that radical, so I took the over but could still see that number being under five.
(If curious, you can find the whole show here:
