If the Wiz are going to take a flier on just one undrafted player, this is who I want to see:
He is huge (listed as 6'10" 300lbs). He put up huge stats last year (18.1/14.2/2.5). Sure, he played for Stanta Clara (who did, it should be noted, produce one pretty decent NBA player), but he still averaged a double/double in his games against Arizona/Georgia/Gonzaga. Heyvelt had big #s in one of the games, but it is hard to tell how much was head-to-head against Bryant.
He was totally under my radar until seeing this from HoopsAnalyst:
