Hard times for the Celtics recently after an amazing start to the season. When you have a team that old, people are bound to get injured. Young guys get hurt too, like Rajon Rondo,missing 8 games in December. Rondo is back in action since it became 2011 but has been struggling to produce like earlier this season. His speed however, is 100% fine, as shown in this play against the Rockets (another Celtics loss) as Rondo needs only 2.9 seconds to run the entire court and beat the buzzer.
