Interesting match-up.
Ground game Nick has the edge, Striking with hands Nick has the edge, Power I think Carlos has the edge, Stamina goes to Nick, and both have good chins.

Carnt wait for this one.

As much as i like GSP, I want Nick to eventually take the title, beating Carlos is a step in the right direction. I guess this will be over 5 rounds is it ? Im going with Nick in the 4th by submission after a brutal standup war.
