I'm sure this is an unpopular view, but how about we give some credit to a great defensive team who came up with a game plan to take away our ball movement?
Basically Orlando did to us what we've done to everyone else in the playoffs.
If Orlando's defense was what shut us down, I'd be worried.
However, it wasn't. Last night's breakdown on offense was almost solely caused by Rondo playing timidly. Orlando wasn't taking away our offense, we just weren't initiating it. That caused us to go to Plan B, which is tough for us when Pierce, Ray, and BBD are the only ones contributing on offense in the second half.
Game 4 was an anomaly, because Rondo is a much better player than he showed. I'm not stressed about Game 5 at all, because Orlando still hasn't shown that they can stop us.
