Tony Parker won the Skills Challenege, but Rondo finished second with a time of 34.7. Rondo actually had to go three times, because he tied with John Wall in the first round at 32.8. He got his best time of the day with 27.5 in the tiebreaker but then finished with his worst time in the final round after messing up the bounce pass part a couple of times.
Rondo may not have won. But all that matters is that he tried. And at the end of the day, that's all you gotta do.
