CHICAGO — Blake Griffin showed up in an orange, black and white sweatsuit. For the record, he insisted there was no Clippers jersey underneath it. In fact, the All-American forward from Oklahoma still wasn’t quite ready to sign a mortgage in Los Angeles or declare himself the NBA’s No. 1 pick. He’ll wait for commissioner David Stern to make that announcement on June 25, even if the Clippers indicated it’s really not necessary. "I’m planning it as if I don’t know right now, which I don’t,” said Griffin, who was in Chicago on Thursday for the NBA draft combine. "I’m not going to guarantee anything. I’m going through it just like everybody else is.” Well, not exactly. While some players are facing a long line of workouts and interviews the next few weeks, Griffin said he’s only scheduled to visit the Clippers next week. And he wasn’t sure he would meet with any teams while in Chicago. The Clippers apparently believe Griffin is the right fit for them. They seemed to wipe out whatever mystery there was surrounding the top pick last week when assistant general manager Neil Olshey and coach Mike Dunleavy told reporters they were taking him. Even so, Griffin isn’t completely convinced. Sure, the team placed photos of Griffin on the team’s Web site after winning the lottery. And on Thursday there was still one showing president Andy Roeser with his suit jacket held open and what looked like a jersey with the number 23 — Griffin’s number at OU — embroidered inside. All evidence seems to be pointing toward the Clippers taking him rather than trading the pick or going with someone else. Even so, he’s maintaining a sliver of doubt. "Nothing’s set in stone,” Griffin said. "Anything can happen, so I’m not going to start buying a house and all that in L.A.” Told of Dunleavy’s comment, Griffin said, "I believe him. If he’s possibly my coach, I believe him. Anything can happen is the way I’m looking at it.” If they go with Griffin, the Clippers can only hope he turns out better than their previous No. 1, Michael Olowokandi in 1998. He went on to average 8.3 points in his career and is out of the NBA — one of many misfires by a downtrodden franchise that has just four playoff appearances. Los Angeles also took Danny Manning with the top pick in 1988.
