It’s crunch time for the Nets, but the team still doesn’t appear to have the necessary chemistry needed to be a real contender.

Nets coach P.J. Carlesimo is concerned, so much so that he has hinted at a change in the rotation. Could we see Andray Blatche in the starting lineup next to Brook Lopez? It’s certainly a possibility.

“Depending on what teams, we also have to look at the big picture,” Carlesimo told reporters. “Some teams it’s going to be a challenge … When we can do it, it’s something we are going to look at.”

In last Saturday’s 96-85 loss to the Bulls, which was the Nets’ fourth in five games, Reggie Evans had 10 rebounds as the starting power forward, but he didn’t score and committed four turnovers. The Nets were in Charlotte last night (Wednesday) trying to avert a three-game skid.

Power forward has been a real sore spot for the Nets this season. Kris Humphries isn’t playing as well as he did last season. In fact, he seems lost since he was taken out of the starting lineup in favor of Evans.

Evans is a fine defender and rebounder, but his lack of offense has been just too much for the Nets to overcome. Inserting Blatche into the starting lineup might be the answer for the time being. Blatche can score and is adequate enough on the boards to compliment Lopez.

None of this means Carlesimo will make a permanent change to the starting lineup, though. “I think it will be more tightening up,” said the coach. He also mentioned that the team will look to get rookie forward Mirza Teletovi more time.

No matter how this works out, getting the rotation back in order should be the top priority for Carlesimo.
