From DX so very solid:
Sources tell DraftExpress that D.J. Wilson is keeping his name in the 2017 NBA Draft and will not return to Michigan.

Our analysis is that this is bad.
Michigan has a couple options to fill the roster spot Wilson is apparently vacating. Illinois State grad transfer Mikyle MacIntosh just withdrew his name from the draft; he's another high-usage, dubious efficiency lower level guy. This is mostly because of his two point shooting. He was 76/44/36 last year on 28% usage. He had a block rate similar to Wilson and could help patch that lineup hole.
The other option is Canadian SF/PF Ignas Brazdeikis, who is currently planning on being a 2018 recruit but is keeping 2017 options open.
UPDATE: It's official.
"D.J. and our coaching staff worked very hard over the last month to get as much information as possible on his draft status," said U-M head coach John Beilein. "Given the data and insight we received, D.J. is confident he is ready to take the next step in his basketball career. We love D.J., and he will always be a Michigan Wolverine. His development over the past three seasons, and particularly this past season, was phenomenal. With continued work, he shows great potential to improve in a similar manner in the NBA. We wish him and his family the very best, and we will always be rooting for him during this draft process and for all the years to come."
