For the Bulls, it’s rather simple. Win their last four games,and they make the playoffs. Of course easier said than done.LeBron James watched from the sidelines, nursing some bumps and bruises, and Antawn Jamison might be joining him there.For a team with championship aspirations, the Cleveland Cavaliers are looking a little vulnerable.Derrick Rose scored 24 points, Kirk Hinrich had 23 and the Bulls gave their playoff hopes a big boost by surviving some shaky free-throw shooting down the stretch to beat the Cavaliers 109-108 with James on the sideline Thursday night.The Bulls moved into an eighth-place tie with Toronto in the Eastern Conference with one more meeting between the teams. Although the Raptors already own the tiebreaker, Chris Bosh is injured.Whoever comes out ahead figures to meet Cleveland in the first round, no easy task no matter how banged up the Cavaliers are. While James sat for precautionary reasons, Antawn Jamison suffered a bruised right foot while scoring 23 points, and both are questionable for Friday’s game against Indiana. Throw in Shaquille O’Neal’s thumb injury, and the league’s top team isn’t exactly a picture of health.Mo Williams of Cleveland led everyone with 35,including six 3 pointers.Luol Deng had 22 points and 10 rebounds, Joakim Noah added 17 points and 15 boards, and the Bulls prevailed even though Rose and Deng each missed two free throws in the final 15 seconds.The Bulls let a 12-point third-quarter lead disappear and couldn’t put Cleveland away after going back up by seven in the fourth. They made enough stops down the stretch, though.Taj Gibson blocked Williams’ layup with 26 seconds left, and Williams missed a turnaround jumper with Hinrich draped on him. Deng then missed two free throws after getting fouled on the rebound with 14.4 seconds left, but the Cavaliers couldn’t take advantage after he missed both shots. Anderson Varejao put up an airball on a jumper after a few head fakes and Jamario Moon had a layup blocked by Noah with 1.9 seconds left.Rose missed two free throws, but Noah got the rebound, preserving the victory. With the league’s best record locked up and the playoffs approaching, Brown is taking a cautious approach with James. The last thing he needs is to see his superstar go down like Bosh, who suffered a facial injury against the Cavaliers, or Milwaukee’s Andrew Bogut.So James watched from the sideline dressed in a suit.

NOTES—Williams scored 12 on four 3-pointers in the fourth, and Jamario Moon added nine of his 14 in the quarter….Delonte West missed his second straight game with lower back spasms….Sebastian Telfair had eight points in his first appearance since the Cavaliers acquired him from the Los Angeles Clippers in a three-team deal….The Bulls’ remaining games are at New Jersey on Friday and at Toronto on Sunday. They host Boston on April 13 and visit Charlotte the following day.
