27) VCU 10-5-1

All records are top 100 opponents only (losses against sub 100 teams are the third number if any). I don't count games outside the top 100 mostly because such teams very rarely win and very rarely play many NCAA tournament games. Florida Gulf Coast won two a couple of years ago, but they were also barely outside the top 100. Such teams are typically 14-16 seeds, so wins are rare.

These rankings aren't a reflection of how good I think each team is, as many have pretty mediocre records or have played very poorly in road games that I wouldn't be confident in their performance.

Kentucky's comfortably above the next tier of teams. I think they should be undefeated going into the NCAA tournament. They're statistically looking like the best team in the last 15 years or so. The closest would be Kansas' national title team (that beat Memphis), and Louisville a couple years ago (also a champion). The "second tier" teams are actually looking a little better than the usual suspects also, but Kentucky looks just that much better. The main key is they have the best defense over that span. Their offense is solid, but not as dominating.

The only "surprise" team in the top 16, (teams that get a favorable early round location usually) would probably be Ohio State (instead of Maryland). They've played really poorly on the road so I would not anticipate them staying up there.

Weakest Teams on the "Bubble"
45) Miami 6-8-1
48) Texas AM 6-7
49) Cincinnati 6-6-3
52) UCLA 5-8-355) Boise St 6-3-4
57) Colorado St 5-2-3
58) Temple 6-6-2
NR) Oregon
NR) Tulsa
I don't track teams that are in the 75-100 range unless they are likely to win a low quality conference, so assume Oregon and Tulsa are roughly ranked 80th.

Best Teams out
30) BYU 3-8 (needs more wins)
34) Florida 2-11-2 (way too many losses)
39) Davidson 5-4-2

Syracuse is ineligible and comes in at 46 (they would barely make it)

So far I'm not sure there's a team that is likely to be screwed by not getting a bid. BYU has a case there, but needs to start winning meaningful games.

Best small conference teams
56) Stephen F Austin
59) Valparaiso
60) Green Bay (same conference as Valpo)
78) Murray St.

There aren't any minor powers that will deserve an at-large bid if they lose a conference tournament right now.
