I'm thinking the net will be cast over a lot of the obvious suspected offenders (UK, UNC, Duke, Louisville, Nova, Cincy, Michigan State) and others (Arizona under Sean Miller has to be a huge suspect, as well as Auburn with Pearl, Tennessee, Miami, FSU, West Virginia).
Teams I think are relatively clean...us, Virginia, obviously the service academies, and probably the Creightons and ETSUs of the world.
Iffy ones...Rhode Island (Seriously, 15 losses in '15-'16 to 10 losses in '16-17 to 3 this year...and only one in-state player on the roster. Yeah, it's a small state, but there are some good players in the Providence area), Xavier, Gonzaga.
