I wonder if underneath the current is that Little Sap, Cooley and Cotton are good eggs with not the most talent but are good for chemistry whereas other DLeaguers like Williams, Johnson, and Benimon were not such good eggs. I think Willaims and Johnson might have had more talent but are not on rosters right now.
I liked Elliot Williams prior to us signing him and during. Despite the fact he didn't get a lot of playing time during games he often played well for the Jazz (I remember him having one bad shooting game). He's been decent for New Orleans - if he works hard and improves he can probably get into a rotation. I'm assuming he didn't have the right attitude for the Jazz and that's why he was waived.
