I don't see Jones and Deng as deserving at all of all-decade. Luol was here for ONE YEAR. He barely qualifies as a Dukie in my book. A good player with tons of potential, sure - but nowhere near a body of work to bump him ahead of several others. I'd say much the same about Maggette the previous decade. As for Dahntay, he was entertaining for sure. But only a 2-year player, and the 4th or 5th option on the team. Henderson, Singler, & McRoberts were/are all better IMO.
Chris D? Absolutely. 4-year player, leader, key contributor to NC team & second FF team, incredible heart, outstanding D, great passer.
Back on topic, I think you can make a good case for Jon to have his number retired. But it isn't stronger, all considered, than the case for Chris IMO, to say nothing of the old-timers (though, IIRC, Tinker never graduated). And it may be a moot point anyway if you need NPOY honors, which is what the Duke U president said in presenting to JJ & Shel. (Hurley doesn't qualify under that criterion, but he was and is the all-time collegiate assist leader, and (I think) a FF MVP. Pretty close.)
