I've got Hunt. He's improved his TDD, still has a solid chin, and can easily connect worse than DC or Cain did. On top of that, I think Silva's last two wins were fairly odd and, while showed heart, showed that he still has bad holes in his striking defense.
On the other hand, if Silva gets Hunt clinched, especially against the cage, I could see him getting the sub. I think a lot of it will come down to how much Hunt has left in his training commitment after these surgeries.
