It's more like the Celtics can't be consistent on offense. They're infamous for their offensive droughts.
Again, in game 2 of the ECF, in game 7 of the 2010 Finals and in 2nd quarter of the last meeting with the Heat, the opponent's D picked up, our offense went south, and the officiating changed. It's never a single factor.
When we had Leon, Posey, House, those were players who could change the pace of the game, Leon and Posey on both ends. We had those type of players this year in Barbosa and Sully, but guess what, they're out.
If Green, Terry and Crawford can bring some offense to keep those droughts from happening.
