Undefeated

I have a couple of questions for thought.
1. Can anyone living beat Ronda Rousey in a UFC match? She took 30 seconds total in her last two fights to annihilate opponents.
2. Will anyone defeat Kentucky before tournament play begins? They soundly defeated Arkansas last night 84-67.
3.  Who even dreamed that BYU would end Gonzaga's home-win streak of forty-one?

Let me know what the answers are when you get a chance.  Lady Grid out.
