Here is the autograph in question.
The basketball camp featured three stars. Isiah Thomas, Joe Dumars, and a younger player who was NOT on the Pistons. I met all three of them and got a signed photo of Thomas and Dumars, but their third NBA player was a rookie, or only a couple years in.
Who was he? It looks like Manut Bol, but it wasn’t. 
If he was #34, then maybe Willie Burton?
Yeah, looking at Willie Burton signatures on Google Images, I’d say it’s pretty likely that’s who it is.
Thank you to you both. The camp was in Michigan and I see that Willie Burton grew up in Michigan, giving him a connection to the area of the camp. Yep, he looked like this when I met him.
I met him after his rookie season and it looks like after that, he became a journeyman player. Good enough to stay in the league for years, but never to rise to prominence.
At that same camp, I got picked to come on the court and play against Isiah Thomas in 3-on-3 basketball. It was a lot of fun and a really clear memory for me. I was lucky to get to play a brief game of basketball against a NBA all-star. Lots of fun.
