I´d have to say yes. Considering the star potential of the top 2 picks, I just don´t believe that the Lakers or 76ers would give that up for a high-risk player like Cousins. Considering that I don't think that Danny would've given those picks up for Cousins either if the balls had bounced Boston's way tonight.
If SAC wants to move on from the Cousins era, this is their highest value opportunity before he reaches free agency. I think dangling a package centered around the 3rd pick + future picks would be the closest that either team gets to a deal.
Personally, I would do it in a heartbeat.
