Speaking on behalf of the Celtics, I'd imagine there'd be some interest.
The Celtics have a ton of draft picks to move, but if a pick from the upcoming draft were available, and how valued 1st rounders have been, they'd only get 2 1st round picks from the Celtics. I don't think they'd give up 3 if a 2014 draft pick were included.
The homer in me doesn't want to move Rondo, Sullinger, or Olynik.
I'm not in love with Avery Bradley as much as most people, although he's been incredible for the last two or three weeks.
We have a 2014/2015 1st rounder from Philly, 2015 1st rounder from the Clippers, a 2016 Brooklyn pick, the right to swap with Brooklyn in 2017, a 2018 1st rounder from Brooklyn, and a ton of 2nd rounders that we'd probably be willing to include. Just nothing from 2014, or you get way less.
I'm not sure Danny wants to do anything that makes the team better right now, seems like he's trying to trade his way into being the worst team in the league. With Rondo coming back though, I'd expect them to start winning at least 40% of their games once he gets going, at least.
