15. Ivy League (37-32 overall, 3-15 vs. RPI Top 100)
Harvard won't be catching anyone off guard after pulling off an upset over New Mexico in last year's NCAA tournament. This conference is more than just the Crimson, though. Both Princeton and Brown are doing a fine job of representing those with outrageous SAT scores. Even with Cornell's 0-10 record, the conference is still five games above .500 on the year.
14. Horizon League (46-42 overall, 3-22 vs. RPI Top 100)
The Horizon has been pretty lackluster since losing Butler before the 2012-13 season, but this could be a strong year. Green Bay has already upset Virginia and nearly upset Wisconsin. Oakland has the worst record of the bunch, but the Golden Grizzlies could upset just about anyone if and when Travis Bader is on fire.
13. Conference USA (87-61 overall, 6-31 vs. RPI Top 100)
These massive conferences are tough to read.
Southern Miss is the only member of the 16-team C-USA with less than two losses, and the Golden Eagles lost by 31 to Louisville. On the other hand, Charlotte won the Maui Invitational and UAB upset North Carolina. The bottom half of the conference is pretty terrible, but any one of the top six teams would be a tough out in the NCAA tournament.
12. Mid-American (53-36 overall, 6-15 vs. RPI Top 100)
Save for Toledo's unblemished record slowly but surely gathering national attention, it's been a pretty doggone quiet month for the MAC. Buy stock while you still can. Eastern Michigan, Kent State and Ohio are capable of hanging with anybody.
11. Missouri Valley (53-33 overall, 7-14 vs. RPI Top 100)
Is Wichita State strong enough to carry the other nine teams, which are a collective 3-14 against the RPI Top 100? The Valley doesn't quite belong in the top 10, but it shouldn't be forgotten about, either. Just ask Dayton and Notre Dame whether Illinois State and Indiana State are any good.
