When a tweet from a senior associate athletic director at UCLA moves the NBA free agency needle, it's a slow news day.

Carmelo Anthony kept the five teams vying for his services waiting on Sunday, which isn't good for anxious executives or fans hitting their refresh button on Twitter.

At one point, Josh Rebholz, the UCLA athletic director, sent speculation into overdrive when he tweeted that Anthony, Kobe Bryant and Kevin Love played pickup basketball at the Westwood, Calif., school. Never mind that all three live in Los Angeles in the offseason, are Olympic teammates and UCLA is a hotbed for offseason games. This seemed enough for some to conclude Anthony had chosen the Lakers.

Later, a UCLA spokesperson could only confirm Bryant had been on campus and that Anthony had visited last week.

This is known: As of Sunday evening, the Bulls hadn't been informed of any decision from Anthony. And unlike some who are living and dying with each speculative twist and turn to this saga, Bulls management merely methodically kept working on contingency plans to improve whether or not Anthony comes.

Some of those have been documented. The Bulls met with Pau Gasol, who turned 34 Sunday, on Thursday in Los Angeles. They have begun preliminary negotiations with Nikola Mirotic, their 2011 draft-day acquisition who is now more likely to join the Bulls this season than next.

And they kept dialogue open with representatives for a multitude of small forwards should they fail to land Anthony. The Bulls have touched base with agents for Chandler Parsons, Paul Pierce, Shawn Marion, Luol Deng and Trevor Ariza, among others.

They also remain in the market for a backup point guard and have talked to representatives for Kirk Hinrich, D.J. Augustin and Ramon Sessions, among others. Though Derrick Rose, by all accounts, looks great in his full-court workouts, the Bulls hope to secure veteran backup help to take defensive and ballhandling pressure off him.

Coach Tom Thibodeau confirmed on draft night that Rose will participate in the Bulls' summer-league minicamp this week. By then, Anthony likely will have revealed his decision. Whether he's a Bull, Rose's recovery and return to form will remain as essential as any ingredient for success next season.
