That ranking does seem to project a lot of improvement, and increased minutes, from Winston, Ward, and Langford. Jaren Jackson likely wont be as good as Bridges, but he's very good and closer to a true stretch 4. Schilling--as a starter or the backup 5--will be a big step up from Goins. But yeah, moving up 4 places in the standing will really require better play and more playing time for the young guys.
I think the parity of this season--with only Purdue really separating themselves, but they're likely losing Swannigan--has made it really hard to call next season. Maryland will need Trimble back and improvement from Rowan, Heurter, and Jackson, to get 1st. Iowa needs to figure out which of the sophomores will do all of their scoring that Jok leaves with. NW needs to learn how to score, same with Minny. Indiana might lose a lot (Blackmon and Bryant, likely, though Im not sure if Archie will persuade them). Michigan needs to replace their best, most important player, and needs improvement/consistency of Wilson and Mo - also learning to run a team through the 4 and 5 will be incredibly interesting to watch.
