Short answer: NO.
Short rationale: Paulie Pancakes needs to stay a career-Celtic. It is part of his identity as a player and he's smart enough and sentimental enough himself to not only know that, but to VALUE that.
Longer answer with no rationale:
#1. I'd have Al Jeff back any day of the week as long as we're not losing PP, KG, Rondo, or Sullinger. Rondo and Sullinger are the only 2 (aside from Bradley but he's my chip here) AlJeff would be playing with in 3 years.
#2. Also, the only way I'd want AlJeff back is if he got to play with KG. The narrative element of those 2 coming together after Al being traded for KG which delivered us 2008 would be too much for me to bear as a fan. I'd be crying with joy every game.
#3. More importantly, AlJeff getting to play with KG is his only chance of living up to his potential. He needs to learn every sort of defense and KG is the only one that will be able to hold him accountable to the point of educating, not berating or scolding. If KG can't do it, no one can.
#4. Sullinger is NEVER going to play the 3. Unless he loses 20 pounds and keeps shooting that 18 footer from the top of the key AND gets quick enough to drive on anyone when he's +8 feet out.
#5. Jefferson is, in deed redundant in the Jazz lineup BUT he is still a valued piece of their offense, and frankly, how could he not be. He is the only low-post slow down scorer in the NBA. Other than being a black hole, he is the only "slow-down" player in the NBA besides every PG trying to eat up clock or Paul Pierce simply because he's old. I love the idea of clock management while scoring in the paint and potentially getting opponents in foul trouble.
#6. I think that's enough points for now. So I'll propose Big Al for Little Jeff Green, Avery B, and picks. OR Al Jeff for Jeff Green and Courtney Lee. + pick? Who knows.
#7. If Big Al comes back to Boston I will try my hardest to change my name to Ras Johan the Green Lion and make the sickest dub song you ever heard.
