A week ago, Glen Davis said he wants to go anywhere Glen Davis can be Glen Davis. At the time, he seemed like a goner. But his comments yesterday were a lot more level-headed and mature. He even told the Boston Herald he would like to return to the Boston Celtics. I’m not sure whether that means anything or he just finally decided to show some diplomacy.

Neither Davis nor Rivers publicly admit to having a problem, though Ainge said he wants the men to talk out their oft-emotional differences if they are to spend another season together.

If that opportunity arises, anyway.

Davis, at least, asserts that he wants to return.

“Man, I do,” Davis said yesterday. “Do you know how much I’ve grown and learned with those guys? I want to keep playing with Ray (Allen) and Paul (Pierce) until they leave.”

Maybe he meant to include Kevin Garnett. Maybe not.

During a chat with reporters, Davis discussed “adjusting my approach to food now.” He claims to recognize the need to change his lifestyle and also understands he needs to “eat for being healthy.” Not just because of basketball, either, although that would obviously become a beneficiary of Davis’s alleged health kick.

“I want to be with my kid forever,” Davis added of his 10-month-old daughter, Amari. “You can’t be 360 pounds and expect to play with your grandchildren. I have to be the player I can be.”

Davis said he just recently realized his own potential as a player, and wants to reach his ceiling. He has hired a sports psychologist, allegedly begun to diet, continued to work out as usual despite the likely lockout, and doesn’t actually hate Doc Rivers as much as it occasionally seems.

“Me and Doc have a good understanding,” [Davis] said. “My name’s Glen and his name’s Glenn. But Doc is Doc. I love the way he coaches. It’s just that me, as a player, didn’t adjust to him. When I first came here, my role was different than it is now. More importance on the team means more adjusting, and sometimes this year I had trouble with that. Mentally, it interrupted my game.

“So I got (the sports psychologist) because of the way I played in the postseason. It helps me to deal with Doc, and why I didn’t play well. Mentally it just became hard for me to see things. Just learn to be myself. I have to be in a zone all the time.”

Glen Davis’s summer is beginning to mirror his season. Ups and downs, peaks and valleys, times he makes me smile and times he makes me scratch my head.
