Inbounds Ball-ball-ball shouting by defender

[crosscountry55]

I would never call this (warning, T, or anything else). Nothing obscene here (so not unsporting in that sense) and there's nothing in the rules about disconcerting a thrower-in or a layupper or really anything else other than a free-throw shooter. "Ball, ball, ball," "dead, dead, dead," "watch the cutter," etc., are all perfectly valid utterances made on a basketball court. Just let 'em play.
