I can respect that, and I'm certainly not questioning Stanley's confidence in himself, yet it seems a case of LeBron's and the bench's gamesmanship getting in his head, rather than the other way around -
"He moves his mouth sometimes. Their whole team does, kind of like their little cheerleaders on the bench. Every time you walk in the right corner. They're always saying something like they're playing basketball, like they're actually in the game. There's only seven or eight players who play, I don't see why the other players are talking. They might as well just be in the stands, in my opinion."
Down 0-2 and he's worried about what the bench says and should be doing - I'd say the mental game is advantage Cavs.
