Wojo updates his twitter with the following:
Butler is going to Dallas, but Wiz and Celts will continue to discuss a scaled down deal for Jamison, source says. Boston still interested.
Cavs and Celts will go head to head for Jamison, but sources say Cavs are very involved in talks for Amar'e Stoudemire.
More details as they become available.
This hasn't been reported, but if you check the trade checker, a deal for Ray Allen and Glen Davis for Jamison and Mike Miller actually works financially. It also maintains roster balance (SG and PF for SG and PF). Thoughts?
Update: SBNation reports that Butler to Dallas is happening. It isn't clear yet what the final pieces are, but the Josh Howard is going to the Wizards and Butler is going to be a Mav.
Update 2: In case you missed it, Steve Bulpett did confirm the Celtics interest in Caron Butler before the deal with Dallas took shape.
Update 3: Ken Berger reports that a Butler/Haywood for Ray deal was discussed:
The Wizards were deeply involved in discussions with Boston that would've sent Butler and Haywood to the Celtics for Ray Allen, but that deal apparently died for a combination of reasons. The Wizards were reluctant to include Antawn Jamison in the swap, and the Celtics were concerned about taking on large contracts as they try to position themselves to remain a threat down the stretch and also to improve in future seasons.
