Conor's been too busy hanging out with Charlie Brown to talk shit.
Also because there was no world wide media tour or bad blood.
And also he has no history in the division. He rose up and fought his way to the title which created drama. There is no history at LW.
He also hasnt established himself as a decent champion, most educated fans who train consider him mediocre skill wise.
Bj Penn vs GSP 2 was epic. Two established champions fighting at WW in a rematch. There was bad blood, a media tour and all the essentials to make it epic.
Conor is good, but the UFC is forcing him down everyones throat with a title shot he never earned (for the second time).
