No, Stevens definitely does deserve some of the blame in game 2 for starting big again. I know that Bradley and KO being out complicates things, but he even admitted it himself that he shouldn't have went big to start the game. Many of us here were saying you must go small to matchup with them, and you have to start off the game that way. After the first six minutes or so once we went small and matched up with them, we played them even the rest of the way, even with as horrible as our offense was.
Amir and Sully are also probably our worst pairing against these guys offensively, because neither of them can spread the floor. So when you subtract Avery from the lineup, add Smart, and figure in the fact that Crowder is a shell of himself due to his injury, you really only have one true outside threat in IT. Thus, they just packed the paint against us. You have to start someone like JJ or go super small with IT, Smart, Crowder, Turner, and Amir to matchup with them, and I guarantee we'll see one of those changes in game 3.
But it absolutely was a mistake on Brad's part to go big to start game 2 again. It cost us another bad start, and though the way our offense was going we would've probably lost anyways, it ultimately kept us from ever being close with the Hawks again in the game.
