Is the time right to trade Tony Allen?

Tony Allen is playing his best ball in years. He's been a key contributor off the bench over the past few weeks. He's averaging 20 minutes, 7 points, 52% FG and 3 rebounds.

Prior to this revival, TA was trade bait because of his $2.5 million dollar expiring contract. You could package Allen (along with Scal) for a veteran who could provide consistent play off the bench.

But….

Now that we are seeing the "good" Tony, should the Celtics keep him?

Or is it a matter of time before the "evil" Tony returns and the Celtics should move him now while his value is at its highest?
