The Spiders have a signature win, but their RPI continues to slip.

Geography could play a larger-than-usual role in this year's NCAA tournament.

Teams fighting for bubble teams and seeding rights were jostled around.

Both Ohio State and Penn are Top 20 in the RPI but under .500 with four weeks left.

New programs, conference realignment and breakout seasons influence the bracket.

Non-conference record weighs heavily in RPI. The ACC and Big Ten aren't hurting there.
