Apparently Silva would like it to be a catch weight fight at 177 seem's fair enough but no word from GSP yet.

I think GSP has a great chance in the fight. Considering Chael got Anderson down in there second fight and pretty easily got mount on him I have no doubt GSP will be able to and he will use it. Anderson doesn't have much urgency off his back nor does he attempt many submissions. I know, I know he got Chael in there first fight but for 4 rounds he didn't really attempt any.
