If people feel the "field is open", let's qualify that as only 8/9 teams at most can reasonably be expected to win the whole enchilada. Of that 8, I think 3 are shoo-ins for the Final Four-Stanford, SC & UConn.
The other 6 all have shown some inconsistency issues against significantly lesser teams:
NC State had a bad loss against NC. Their other loss against VPI was without Cunnane. They are my 4th Final Four
Texas A&M was getting too much promotion by Carolyn Peck last night. Yes, they have beaten many top 25 teams-all in the 10-25 range and none in the top 9 (KY-#10, AK-#13/#16, MSU-#14, TN-#16, DePaul #19, GA-#22 and Texas #25. They lost to LSU and they haven't played SC. Their most impressive wins are probably over Arkansas 74-73 and 69-67. This team has had too many close games against mediocre teams for me to think they can make a serious run.
Arizona lost to Stanford (no shame) and to Wash St after blowing a big lead. They did crush Oregon last week but to me, they are still too one dimensional with Aari. Cat Reese has stepped up nicely recently but I think UCLA is better talent-wise.
Which brings me to UCLA and as just noted this is a Final Four talented team with a Sweet-16 coach. Close simply cannot manage close games. This team could make a serious run or get beat by a better tactician like Doug Bruno.
Louisville is my 8th possibility, however this team is as reliant on one player as any team-Dana Evans. Their one loss highlights a weak ACC conference and their lack of an inside presence and rebounding makes them susceptible.
Baylor, while looking good against a 35th-40th ranked offensively challenged Texas team last night, simply has inconsistent outside shooting and lacks a true point guard. I'd be impressed if they made the elite 8. I do not think this team can handle good guard play.
The other team I would mention is Maryland-winning the Big10 is nice but again, this team has holes when compared to the elite 8 schools above. Owusa has been very good, I am just not sold on their front court and peripheral supporting players to match up against the others. Plus, Brenda has a way of self imploding when the favorite.
