That makes no sense what so ever.
So you suggest anderson and gsp both weigh 170 but no 170 belt on the line. Then you suggest if gsp loses he just gives it up? Then why in the world wouldnt it just be for the belt anyway?
That makes zero sense.
-because GSP wants the fight only at 170
-because Anderson can't be going up and down defending belts
-because GSP can't keep the belt if he loses
-because it's the only way the fight will ever happen
use your brain and stop being a dick, seriously, your need to be right is making you arrogant and annoying
