The pregame optimism that hovered around the Celtics  disappeared early in the first half when Shaquille O’Neal  limped off the court with what the team is calling a strained right calf. Shaq didn’t return and there was no further update provided. His future is uncertain at best. The good news for the Celtics is that Nenad Krstic ‘s knee injury is much less serious than first feared and there’s a chance he can return by Tuesday.
As for the game, the Celtics got a much-needed 101-90 win over Detroit to stay tied with Miami in the loss column for second place in the East. They built a double-digit lead in the second half and had some anxious moments, but were able to hold off a Detroit team that is playing out the string.
WHAT WENT RIGHT
Nenad Krstic will be back soon: The best news the Celtics received over the weekend is that Krstic suffered a bone bruise and didn’t do any further damage to his right knee. Krstic said that he hoped to return to the lineup on Tuesday when the Celtics host the 76ers. He has some pain in his knee and there is swelling, but all things considered this couldn’t have worked out better for him or the team.
Three of the big four isn’t bad: Paul Pierce  scored 22 points, Kevin Garnett  had 23 points and eight rebounds and Rajon Rondo  dished out 14 assists. Now the Celtics just need to get Ray Allen  going. They ran their first play for him and he got a wide-open jumper, but Allen later collided with Rip Hamilton and had to leave the game early in the first quarter. He finished with 13 points, but on just six shots.
Delonte West  is doing everything the Celtics hoped he would: Delonte West had a lot of expectations to live up to when he returned from his wrist and ankle injuries, but he’s surpassed them most nights. West had one of his better all-around games with 10 points and five assists, while playing the kind of strong defense at two positions the Celtics desperately need.
WHAT WENT WRONG
Shaquille O’Neal’s return didn’t last long: For five minutes of the first quarter, Shaquille O’Neal was back on the court and all was well. But when he pulled up lame at midcourt and hobbled off, the Celtics were right back where they started in regards to the Big Fella. The team is calling a strained right calf.
Too many turnovers: The Celtics shot 62 percent in the first half and held the Pistons to 41 percent shooting, but they had only a one-point lead. The problem was too many turnovers. They had 11 in the half and seven in the second quarter alone. That kept the Pistons in the game.
