[Duncanoypi]

Any idea?....Is there an undraftee who won this award?

In the recent history, Mark Jackson in 1988 with the 18th pick.
In 1958, Woody Sauldsberry with the 5th pick of the 8th round (60th overall pick)

[Peter]

I was going to say Kemp but his rookie year was the same as DRob's and he was the #17 pick in the '89 NBA Draft.
