as for the field, the Pac 10 is so horrible that there's no way a 12-9 Arizona team should make the Tourney, I think the Pac 10 has been watered down to a 1 bid league with how atrocious it's been
I don't think Maryland has done enough to get in either.
Illinois and Seton Hall(due to their wins over Pitt and Louisville*whos after them*) should get the nod for the Tourney over Arizona and Maryland, that's my thought
