This fight is so interesting. I don't think Alves has a slight edge in the standup, I'm going to go ahead and say he has a pretty significant edge in the stand up. If he can mask those leg kicks with jabs and combos like he did in his fight with Koscheck, he can really beat GSP. Walker, you said Koscheck's wrestling looked off, and yes some of it may be due to to the 2 weeks notice, but I promise you most of it was due to those vicious leg kicks. You just can't plant and drive well after taking that kind of punishment.
Alves's TDD looked great and has looked great, and although I think GSP will eventually take him down, I feel he will take quite a bit of damage before doing so. I'm pretty intrigued with this eventual matchup.
