The end of the Celtics  14-game winning streak came inauspiciously. For 45 minutes, they had controlled their matchup with the Orlando Magic , and then in the final three minutes and 20 seconds, everything fell apart in an 86-78 loss. The Celtics were outscored 15-1 over that span as the absence of Rajon Rondo  finally caught up to them.
Nate Robinson  shot 2-for-15, Ray Allen  shot 3-for-13, and Paul Pierce  once again had to direct the offense instead of working into the flow. The Celtics have felt for weeks that they weren’t playing their best basketball, but still they found ways to win. It was only a matter of time until that run ended, but it was still something of a shock that it fell apart so quickly in game they seemingly had in their back pocket.
WHAT WENT WRONG
The limits of Nate Robinson as a point guard: It’s been said again and again that Robinson is not a true point guard, and he’s not. The Celtics have tried to figure out a way to play with Robinson in place of Rondo that allows him to be him, and also allows them to continue to function as a pass-first, unselfish unit.
But in order for that to work, Robinson has to make shots. The Magic laid off Robinson and let him fire away from the perimeter. He was 0-for-5 in the first half and 1-for-10 before he knocked down a wide-open 3-pointer. When Robinson did go to the bench, the Celtics went with Avery Bradley , which was more about defense than running the team.
The Celtics not only don’t have a point guard right now, they don’t have a backup either. That is took this long to catch up to them is a testament to all the other things they’ve done well, but it was only a matter of time.
J.J. Redick is Ray Allen’s Kyrptonite: Once again Allen had a dreadful time shooting the ball against Orlando, and once again Redick was with him every step of the way. It’s been like this since the 2009 playoffs and it’s well past time to give the former Duke sharpshooter his due. He’s become much more than just a jumpshooter, unfortunately for Allen.
Jermaine O’Neal  will need some time: O’Neal’s return came at the perfect time with Semih Erden feeling ill, but it was clear watching him play that he’s going to need a few games (at least) to get his conditioning back. There’s no sugar-coating this: Jermaine O’Neal has been a huge disappointment so far this season.
However, there is ample time for him to save his career and salvage his reputation in Boston. If the Celtics are going to do what they want to do this season, they will need him and in order to get there he’s just going to have to burn minutes.
WHAT WENT RIGHT
Even without Kendrick Perkins , the Celtics still had the right gameplan for Dwight Howard : Without Perk, the Celtics went on the offense to defend Howard. They did this by pounding the ball in to Shaquille O’Neal  early in the game in the hopes of getting Howard in foul trouble. It worked as Howard picked up his second late in the first quarter and was in foul trouble again early in the third quarter.
Howard continued to be his own worst enemy, getting called for a 10-second violation on a free throw attempt and compounding that by getting a technical foul. He didn’t score his first basket until a minute into the fourth quarter. The Magic’s trades were all about helping Howard, but if he is going to ascend to true MVP-level, he still has to learn to help himself against teams like the Celtics.
Defense, defense, defense: The Magic shot less than 40 percent and Howard never got going. This loss was all about the offense. The defense was once again, dominant.
Paul Pierce as point forward: For one half anyway, Pierce was the best point guard on the floor, scoring 16 points and dishing out four assists as the Celtics took control. The Celtics are asking a lot from Pierce, and this time they may have asked too much because he wasn’t able to build on his first-half performance.
