Your logic is flawed, Pettis just beat Bendo for the second time, this time first round submission. Clear cut victory, why the hell would he get an instant rematch when there are several others more deserving waiting in line? Ridiculous.
Exactly, it's not like the fight was controversial. Pettis forced Benson to tap and give up because he popped his arm with a beautifully executed submission. Benson needs to get back in line and earn a rematch down the road because there are also other fighters more deserving of getting the next shot at the new champ at this point.
