9:28am: In spite of rumors that Bynum could make his decision today, the Mavs still expect him to visit tomorrow, according to the Cleveland Plain Dealer (via Twitter). Meanwhile, the Cavs are hammering out the specific terms of their offer to Bynum, according to the Plain Dealer (via Twitter).
9:05am: After sitting down with the Cavaliers on Monday, Andrew Bynum will meet with Hawks officials today, and could have a contract agreement in place within the next 24 hours, reports Ken Berger of CBSSports.com. Berger hears from a source that there "should be a deal today."
When the Cavs met with Bynum yesterday, they reportedly made him a two-year offer worth $24MM, with a team option on the second year. Despite Cleveland's serious interest, the free agent big man planned to proceed as scheduled to meetings with the Hawks and Mavericks, as ESPN.com's Marc Stein tweeted late last night.
Presumably, Bynum's meeting with Dallas isn't also scheduled for today, so if he makes a decision tonight, that may rule out the Mavericks. Berger's report seems to be somewhat at odds with Stein's, as the ESPN.com scribe also tweeted that he thought the Cavs viewed Dallas as a much more serious threat than Atlanta.
In any case, it seems Bynum will end up committing to either the Cavs, Hawks, or the Mavs at some point this week, perhaps as soon as today. All three clubs figure to be interested in the 25-year-old on a short-term, incentive-laden contract. As Stein tweeted last night, the Cavs' interest in Bynum stems from the fact that he's a potential All-Star center whose lost 2012/13 season makes him very attainable, and I'd imagine the Hawks and Mavs are thinking along the same lines.
