Ken Berg wrote a great piece about Delonte West’s bipolar disorder. I believe this is the first time West has ever explained why he was driving a three-wheeled motorcycle with three guns, an 8-inch knife, and more than 100 rounds of shotgun ammunition. He says he was just transporting the weapons from his mother’s house to his own, that his bipolar disorder had nothing to do with it.

“It was a bad decision,” West told Berg. “It had nothing to do with being in the right place or not.”

West’s battle with bipolar disorder, he says, is going well. He points to the Thunder game, when he missed a three-pointer from the corner that would have tied the game. Before he began receiving medicine, West says, the miss would have affected him for hours. That’s what bipolar disorder does — it makes good things seem even better and bad things seem even worse. But an hour after his miss, West was okay to talk to reporters about the shot.

“When I was younger and I didn’t have the proper care and medicine, I would’ve been in here all day,” West told Berg. “The guys would’ve had to come get me and say, ‘It’s only one game, man. We’ve got another game.’ But to me, it would’ve been like I just lost a Game 7.”

West says he already knows how this season is going to end.

“There’s only one way it’s going to play out,” West told Berg. “I want it to play out that way and it’s going to play out that way. And that’s holding the trophy at the end of June. Man, that’d be a strong chapter in the book or the movie I’m going to write one day.”

But as West should know by now, there are a lot more important things than the Larry O’Brien Trophy.

Update: Doc Rivers on West, from the Boston Herald.

“Every day is a better day for him is the way we look at it – as a person and as a player,” Rivers said. “Wyc (Grousbeck, C’s co-owner) probably wouldn’t want to hear about this, but at the end of the year if he came out of this and didn’t help us basketball-wise but was great as a person for the rest of his life, then in my mind we’ve done something very good here. But if that happens, then he’s probably going to help us on the floor, too.”
