All that said, let's run through the whole league and attempt an early (really, really early) guess at where they rank:
1. North Carolina
Last season: 26-12, fifth in the ACC, Sweet 16.
Key players leaving: G/F J.P. Tokoto.
Key players returning: G Marcus Paige, F Justin Jackson, F Kennedy Meeks, F Brice Johnson, G Nate Britt, G Joel Berry.

Key players returning: G Grayson Allen, G Matt Jones, F Amile Jefferson, C Marshall Plumlee.

Key players leaving: G/F Justin Anderson, F Darion Atkins
Key players returning: G Malcolm Brogdon, G London Perrantes, F Evan Nolte, C Mike Tobey, F Anthony Gill.

Key players leaving: G Jerian Grant, G Pat Connaughton.
Key players returning: G Demetrius Jackson, F Zach Auguste, F Bonzie Colson, F V.J. Beachem, G Steve Vasturia.
