Looks like a 4-way tie at 14-9 right now. If UCF wins tomorrow I believe they clinch the top seed. If USF wins, it depends on the results of the UConn and Houston games. At 15-9, if my tie-breakers are correct:
USF/UConn/UH: USF
USF/UConn: UConn
USF/UH: USF
If USF/UCF gets rained out or has no decision, UH can be the 1-seed with a win. If they lose then UConn can get it with a win. If both lose, then USF. If all three games get washed out, it should be USF.
These are unofficial, based on past years' tiebreaking procedures. Simplified, for USF to be the top seed, I believe we need a win, plus either a loss by UConn or a win by UH (or both).
