I'm rooting for Lopes in the next card because I want to see him fight for the belt again. And watching him fight is truly exciting to watch; he brings a lot to the UFC and to the viewers, and he's also a very charismatic guy.
I love them both as fighters. But from what I've seen, Silva is more methodical out there as Lopes tends to just throw as hard as he could when he see the opportunity. Silva on the other hand sets traps so he'll prolly use Lopes' own tendencies against him.
But just from line value alone, I wouldn't blame anybody for taking a shot at Lopes as a decent underdog at 3.15. Lopes is def being disrespected in this spot... And I wouldn't be surprised if if the lines move closer as the event draws closer.
