Okay, so the similarities between this song and the Boston Celtics ends with the first line, “Cuz it’s all in my head.” But it’s a good song, and I like it, and this is as good an excuse as any to use it on the blog.

Kendrick Perkins thinks the Celtics problems are all in their heads.

“You can tell by the start of the first quarter,’’ he said. “However we come out in the first quarter, that’s how the game is going to be.

“If you get a lot of defense, a lot of energy going from the older guys more than the younger guys, then we are going to have a pretty good game.

“I don’t think it’s talent. I don’t think it’s physical. It’s all mental.’’

Perk, like his team’s play would indicate, just wants the regular season to be over.

“I can’t speak for everybody else, but I am kind of ready for the playoffs,’’ said Perkins, who finished with 7 points and 9 rebounds in 24 minutes last night. “Let’s get it on, and whatever it’s going to be, we’ve got to go all in and let the chips fall where they may.

“When the playoffs start, everybody knows how it is. It’s a different atmosphere, make sure we come in with the right mental [approach] and the guys work how they need to work and go from there.’’

Do the Celtics really think the playoffs will come, and they’ll turn a switch? Is it that easy? Do they really believe the playoffs will cure everything?

I’m not sure if they believe it, and I’m not sure if I do either. This regular season has been so painfully inconsistent and troublesome for so long, I don’t know what to think about the playoff prospects. The C’s have enough talent to win the whole enchilada, but there’s been something missing for a long time.
