At the moment, I have the following four teams as #2 seeds ...
Nebraska, Alabama, Louisiana, and West Virginia (no particular order).
I also have the following eight #3 seeds (no particular order) ...
#38 UNCW
#43 Charleston
#40 TCU
#47 Illinois
#41 Connecticut
#32 UCF
#30 Florida
#48 Texas
An additional six #3 seeds will be taken by auto-bids. A seventh #3 seed will be taken by an auto-bid if Penn State steals a bid by winning the Big Ten tournament tomorrow. The above 8 plus the 6 auto-bids leaves two additional at-large bids (as #3 seeds). All of the #4 seeds will obviously be auto-bids.
For the last two at-large bids, we have the following schools competing. I will not breakdown their resumes here. But this gives you an idea of what the bubble looks like. And if Penn State wins tomorrow, there is only one at-large bid available for the below bubble teams.
#34 Northeastern
#35 Coastal Carolina
#39 Xavier
#44 James Madison
#45 Kansas State
#46 Georgia Tech
#51 Oregon
Neither #42 Maryland nor #49 Auburn has done enough in my opinion (poor conference play) to earn an at-large bid. Neither team qualified for their conference tournament.
I do not think Troy makes the field. I also think that Georgia Southern must win tomorrow to make the field. Coastal Carolina and James Madison are some tough calls ... along with Georgia Tech, Northeastern, and Xavier. One set of metrics working to the advantage of Coastal Carolina (besides the RPI ranking) ... #21 SOS, #3 NC SOS, and #12 NC RPI. The committee may reward them for scheduling tough. If Georgia Southern wins tomorrow, that could knock Coastal Carolina out ... or it could give the Sun Belt a fourth bid (shutting the door for every once else in the above list).
If Penn State wins tomorrow, the Sun Belt cannot earn four bids to the NCAA Tournament, if what I have in the #3 seed list above is correct.
