Derrick Rose added 14 points and 11 assists, while John Salmons also scored 14 for the Bulls, who posted their second straight victory. Taj Gibson ended with 11 points and seven boards. Joakim Noah, who also converged on James in the final crucial Cavs offensive play, pulled down 11 rebounds to go with seven points.

"It is good that we are getting some stops when we need to," said Bulls coach Vinny Del Negro. "We need to make some more shots to be more effective and score a few more points but that will come. It was an excellent win for us and I am happy for the guys. I was happy more with our energy, our approach and our emphasis the final five to six minutes of the game being able to make plays."
