First off, yeah it was a bad idea for Rondo to dribble into the corner. You just should never do that. Rondo could have passed to KG but it would have had to have been a long two or a three atte.OT for KG. Smith might have deflected the pass though.
Ultimately, I can't blame Rondo too much though. It was just a tough spot, especially for a guy who rarely ever has the ball in thy type of situation.
As a side note though. The refs actually screwed up the call though. It probably makes zero difference, but Rondo actually lost th ball out of bounds with about 1.5 seconds left on the clock. Maybe a miracle happens.
Oh well, put them away Thursday, and it's water under the bridge.
