DJO went to Marquette and he's had a lot of exposure. Even his teammate at Jae Crowder is getting some attention on the Mavs, and he was drafted & traded as a 34th pick.
If DJO and Crowder turn out to be decent pros, more than likely scouts underrated them (by overrating them) for going to a high-profile school and playing with other high level recruits.
There have been bigger misses in the draft, so I think it's entirely plausible Mitch is hiding him. Directly related to Pau deal? Who knows... 2nd round picks like DJO are thrown in all kinds of trades, sometimes for just salary dumps/picks.
But I think developing Morris had more to do with it.
