It took a quarter for the inevitable letdown to kick in, but the Celtics  wandered through a disastrous second quarter Tuesday night against the Kings that not only saw them give up 34, it also gave their young opponents a shot of confidence. The good news for the Celtics is they recovered quite nicely with a strong second half in a 95-90 win that capped off their successful west coast trip on a winning note.
The win also means that Doc Rivers  will be be the head coach for the Eastern Conference in the All-Star game, a nice tribute in what has been a tremendously rewarding season thus far.
WHAT WENT RIGHT
The aggressive Rajon Rondo  is the right Rajon Rondo: It was good to see the point guard carryover his second-half play against the Lakers into this one, and the Celtics desperately needed it. Rondo went to the basket early and often in the first half, even passing up could-be assists for sure-thing baskets. This is the Rondo that captured the imagination during the playoffs last season and the one that keeps opposing defenses on its heels because of his unpredictable style. This is the Rondo the Celtics need in the second half of the season.
Ray Allen  is closing in on Reggie Miller : It’s only a matter of time now before Allen becomes the all-time 3-point king. He made four more Tuesday and is now nine away from passing Miller for the most 3-pointers made. On an up-and-down night, Allen was consistent throughout, just like he’s been throughout his remarkable career.
Kevin Garnett  brought the good kind of crazy: After a so-so first half in which Garnett didn’t do much to distinguish himself, he brought out the insanely-intent version for the final 24 minutes. Garnett was all over the court, the floor and the boards. Whether it was aggressively challenging DeMarcus Cousins  at the rim, or diving on the floor to come up with a steal, Garnett turned it on big-time in the third quarter. Not surprisingly, the Kings made only 6-of-19 shots and scored 17 points as the Celtics reclaimed the lead.
WHAT WENT WRONG
Time to start Perk? Shaquille O’Neal  is either hurt or just not into it right now, but he is not giving the Celtics any kind of production as the starting center. Kendrick Perkins  meanwhile is still looking to find his rhythm just five games into his return from knee surgery. However, it seems like it’s only a matter of time before Perkins rejoins the starting lineup and with an upcoming slate that features the Mavericks, Magic, Lakers and Heat in the next week and a half, the time may be right for the switch.
Putting out an APB for the bench: Starting Perkins would of course send O’Neal to the bench, which was the game plan all along. Rivers envisioned Shaq being a low-post scoring threat off the bench who would open up the perimeter and also create attention and space for Glen Davis . The Celtics second unit needs something right now because outside of Davis they all seem to be struggling. On an encouraging note, Nate Robinson  gave the Celtics strong minutes in the second half and even closed out the game.
Slow down, you move too fast: One of the Celtics bad habits against bad teams is to get into an up-tempo game against them. The result is often turnovers and missed opportunities in transition. The Celtics turned it over 15 times, which contributed to their lackluster play in the first half.
