Danny Ainge shot it down , telling the Globe that he has not talked with the Wizards. It also prompted Allen to post the following on Twitter : “I have no control over trade rumors people. Let’s just focus on being positive. I am a Celtic. Green all day.”
Washington Post beat man Michael Lee also took to Twitter to knock it down .
There is some thought that the rumor was put out there as a way to get other teams to sweeten their offers for Butler and Jamison. The Cavaliers , for example, have been rumored to be in pursuit of Jamison, but are said to be unwilling to part with second-year forward J.J. Hickson.
The following is the initial reaction to the rumor:
Yahoo’s Adrian Wojnarowski offers up an intriguing trade rumor  with the Celtics potentially dealing Ray Allen, Brian Scalabrine  and J.R. Giddens to the Wizards for Caron Butler and Antawn Jamison . If it happens the deal would fundamentally make over both teams.
Wojnarowski writes that “the trade isn’t imminent.” The Wizards have been talking with several teams, notably the Mavericks, about dealing Butler but this is the first scenario involving both Butler and Jamison.
Washington’s motivation is simple. The franchise is a mess in the wake of the Gilbert Arenas  fiasco and it is loaded down with huge contracts for its veteran stars. Allen, Scalabrine and Giddens all have expiring contracts and a deal like this wouldn’t just be the first step in blowing it up and starting over, it would be the T.N.T. and the dynamite.
Butler is signed through next season at over $10 million and Jamison is signed through 2012 where he will make over $15 million. For the Celtics, a move like this would add significant money to the payroll, but it would also accomplish Danny Ainge’s stated goal of a trade that would help them win now and in the future. They would be getting two former All-Stars, and with Allen’s decline this season, the two best players in the deal.
Butler’s career has read sort of like Pierce-lite and while he has played some 2-guard, he is not the same caliber of long-range shooter as Allen (Butler is a career 31 percent shooter from 3-point range). According to 82games.com , he has played 72 percent of his minutes at the small forward position this season. Jamison will turn 34 this summer, but he has been remarkably durable during his career, playing 82 games five times in his 12-year career.
Both players have shown versatility during their careers. Jamison came off the bench during his one season with the Mavericks in 2003-04 and wound up winning the Sixth Man of the Year award. He would obviously be a significant upgrade to the second unit if Garnett is healthy, and provide better Garnett insurance then Rasheed Wallace  has been able to give.
If Butler can make the transition to playing alongside Pierce it would give the Celtics two rugged scorers and defenders on the wing. It’s worth noting that he has played alongside Dwyane Wade  and Kobe Bryant  at various points in his career.
Of all the rumors that have been presented, this one has the most realistic and interesting possibilities.
