This is just for fun ... based on the other data I'm tracking, I made a composite ranking (1/2 RPI, 1/6 Pomeroy, 1/6 Sagarin, 1/6 BBState) and graphed it over the past month and a half. I'm putting the NCAA bubble line at 50. Mississippi State is the closest to crashing the party, with Florida the most tenuous of the teams on the inside.
Let me know what you think!
