When looking at the depth chart, prior to the commitment from John, there was a clear weak spot at the center position.
In four seasons as a Golden Eagle, he tallied career splits of 5.5 points, 4.3 rebounds, and 1.5 blocks per game while shooting 57.5 percent from the field.
His bulky 6-foot-9 frame gives him the ability to set hard screens and allow for multiple pick-and-roll opportunities.
He might not provide offense at a high clip, but John can get a basket when needed.
With a star-studded team like Duke has in store, John fits great due to the fact that he doesn’t take touches away from the main sources of offense, likely being Paolo Banchero, AJ Griffin, and Trevor Keels.
