I know this isn't exactly a surprise to anyone, but just came across this in the LA Times

Kevin Love and Darren Collison have probably played their last games for UCLA and will make themselves available for the NBA draft, sources close to the players said today.

Both players confirmed their decisions in separate meetings with UCLA Coach Ben Howland on Monday. The sources spoke on the condition of anonymity because they were not authorized to make an announcement until after Howland holds a season-ending news conference on Wednesday afternoon.

Love, a 6-foot-10, 270-pound center, led the Bruins with averages of 17.5 points and 10.6 rebounds. The freshman was Pacific 10 Conference player of the year, a first-team All-American and most outstanding player of the NCAA regional at Anaheim. Collison, a junior point guard, was a third-team All-American.

Love and Collison are expected to hire agents, which would mean they could not return to UCLA next season.

While I am obviously disappointed, best of luck to these 2 great athletes.

The same article also speculates that Westbrook is likely to go as well:

The Bruins are also expected to lose guard Russell Westbrook, a sophomore. He played opposite Collison but moved to the point when Collison was injured early this season.

One scout projected Westbrook as a possible lottery pick, and the guard's family has indicated that he would probably leave school if expectations were that he would go early. He had a career-high 22 points against Memphis and, at 6-3, 190 pounds, was clearly the one UCLA player physically suited to run and jump and bump with the Tigers.

The end of the same article also seems to suggest that Nestor's nuclear scenario (losing up to 7 of the current players) is a distinct possiblity. Let's hope Howland has some contingency plans in place. Go Bruins.
