I've seen this crap on another site. Simple fact is, that if they didn't give GSP the extra time, Diaz wouldn't have been in a title fight. If anything, it was for Diaz's benefit that GSP be allowed extra time. It's not like if he missed weight, they'd just cancel the fight, it'd turn into a 5 round non-title fight. The extra time benefited Diaz more than GSP. At least the extra time gave Diaz the opportunity to fight for a title rather than be dominated in a 5 round non-title fight.
