It could be a coincidence that he got T’d up in two consecutive games, but otherwise I agree. The first one I thought was for “flexing” which seemed kinda petty by the ref. This one was likely for using a bad word around the ref. Either way I hope he maintains self control and stays on the court.
In the postgame recap they asked what he said for that first T, and he said "And One!"... to which the hosts joked that that was a "cleaned up" version of what he said. Throw a couple choice expletives in there and aim it at the ref, who hadn't actually called a foul, and that ref could have easily felt like he was being cursed at.
For last night's T, he was called for a foul and then said something to the ref, who immediately T'ed him up.
He definitely needs to clean that up, because he won't get any benefit of the doubt from here on out from other refs.
