This is yet another reason you have to respect Delly.
I imagine Delly as more a basketball intellectual who isn't very superstitious and wouldn't feel too attached to a playing number. Although I should cite this from a St Mary's article about basketball superstitions:
"Matthew Dellavedova, aka Delly, claims he doesn't do anything too crazy but admits, "I have a Wolverine figure that one of the coaches' sons gave me and I make sure I put his claw's out when it's time for the game."
So long as Deng doesn't touch his Wolverine figure, he should be alright.
