I think four is pretty realistic as it stands right now...and it would be a tough call on which four. Temple is in the driver's seat -- then URI would probably be #2, then Xavier and Richmond.
But the gap between #2 (URI) and #6 (Charlotte) is very, very small. Both Dayton and Charlotte are very close and it's all going to depend on how the rest of the A-10 season and tournament play out.
There's a small outside chance they could get five teams in, IMO.
