Well I'm pulling for Cal but I could easily see any of the top 4 seeds taking this thing. I would be very surprised if it was one of the other 4 teams, shocked really.
I'd say LSU because I really like Beth Torina and what she has achieved at FIU and LSU but they can't be relied on to score enough runs to win it all. USF will at least give their pitchers some runs to work with most nights.
Also you have to respect a University calling itself the University of South Florida which is NOT actually anywhere near South Florida.
