Man this is a tough decision. I can see Matt being the one to pull-off the upset on Mac, but I personally think Mac will win based on his perormances I have seen thus far and his experience alone.
I can also see Tommy being a tough match-up for George if he can impose his wrestling (however it would be nice to see him atleast attempt to pass guard this time). George is a very techinical fighter though, and if he can avoid the take down and use his technique to keep it standing it will be a bad night for Tommy. What do you guys think?
