With the NBA trade deadline arriving at 2 p.m. Thursday, the Bulls continue to explore adding a shooting guard, perhaps the Rockets' Courtney Lee or the Grizzlies' O.J. Mayo - on their terms. That translates to offering draft picks and absorbing money into their roughly $2.9 million of salary cap space. A player would have to be included to offset the remainder of Mayo's $4.45 million deal, but a league source said the Bulls are rebuffing teams' requests for Omer Asik and Taj Gibson for now. Coach Tom Thibodeau said Tuesday's acquisition of another first-round pick for James Johnson "gives us flexibility moving forward." The Bulls don't feel pressure to make a deal. Familiar face: He wore a headband, which the Bulls prohibit. He changed from No. 16 to 0 because he wants "to start from zero and work my way up." But the biggest change for Johnson was he actually started at small forward, one day after being pulled from practice early and traded from the Bulls to the Raptors. "I'm not disappointed at all," Johnson said. "It's a business." Johnson finished with nine points and five rebounds in 26 minutes. "I'm just trying to develop a little more," he said. "I know these last two years I was not playing as much. It's hard to develop when you're sitting down." Raptors general manager Bryan Colangelo revealed he had a 2009 draft-day trade in place to move down with Johnson as the target if DeMar DeRozan had not been on the board at No. 9.
