To answer the OP, with a healthy IT, I do think we match up better against GS than we did against Cleveland. Our lack of rebounding and interior D wouldn't be nearly as exposed against the Warriors as it was against the Cavs. I still don't think we could win the series, but we'd have a chance to steal a game if Durant isn't hitting his shots in a particular game.
That being said, I don't think the Warriors have this thing wrapped up yet. I'm expecting one or two Cavs role players to catch fire in Game 3, and Irving is due for a great game as well. I'd give the Cavs a 60% chance to win Game 3. If those things happen and the Cavs win, though, LeBron will get - and gladly take - all of the credit for the win. If they lose and trail 3-0, no matter how well everyone else plays or how well he plays, LeBron - or his people - will publicly point the finger at someone else.
