My favorite is his dive/steal from Jason Williams in GM 4 of the Magic series.
But my second favorite is actually a game where he dominated on the defensive side of the ball. GM 6 vs the Lakers in '08. I vividly remember the first quarter when RR kept breaking down the Laker O, and Phil Jackson told his team during a timeout that Rondo was killing them. That made me so happy!
RR has certainly had some amazing highlights over the years. It makes me wonder what he can do once he has a running squad alongside him. Expect to see a lot of alley oop highlights to JG(hopefully) and JJJ in the coming years!
