I also like this idea, but I wonder if Zeller + #31 would be enough to pry away Oubre. I don't like the idea of swapping in Sullinger for Zeller, because I think in a year like this (when the team has relatively high expectations and team chemistry is a factor) it's tough to shed Sullinger, even if he's at the end of his deal.
The value of adding players like Oubre is that you could stash in in Maine (couldn't you?). So let's say at the end of the year you had three guys -- Oubre, Young, and Mickey -- who all tore it up in the D-league and are all young and have lots of time left on their deals. Then when you go for that big mega-deal for a star, you can add on to a centerpiece asset (like a Brooklyn pick) with other nice sweeteners. That's essentially what happened with the Garnett deal, when we sweetened the headline piece (Al Jefferson) with similar sweeteners like Ryan Gomes and Gerald Green.
