The latest intel on No 1.-ranked prospect Marvin Bagley coincides with the Duke surge in his Crystal Ball.

Duke is up to 50 percent in Bagley's Crystal Ball, with the 6-10 power forward scheduled to officially visit next weekend. The Blue Devils are believed to be in a strong position with Bagley, and I have changed my Crystal Ball pick from USC to Duke.

Sources continue to tell 247Sports that the ultimate desire for Bagley is to be a 2017 prospect and play college basketball this season. Whether or not Bagley, who is currently the No. 1 ranked prospect in the 2018 247Sports Composite, can become eligible as a 2017 prospect has yet to be determined.

Arizona and Kentucky are also in the mix with Bagley.
