Some would say so. It's certainly big news in this house. If it helps, think of it like this: Angel McCoughtry was, apparently, to Marynell Meadors as Demarcus Cousins was to Paul Westphal.
It will be interesting (maybe not to you) to see whether McCoughtry's attitude problem mysteriously disappears after this: Atlanta's next game is tomorrow, against, arguably the worst team in the league (Phoenix has the worst record, but they're in the tank for Griner).
