1. Instant rematches should only happen when the first fight was unbelieveably close/controversial. Eg GSP-Hendricks, Jones-Gus etc. But there was nothing controversial about this fight: Hendricks beat Lawler 3 rounds to 2. Lawler had his fair shot and got defeated. And not even Gus got an instant rematch. 2. Instant rematches should only happen when there are no other viable contenders. But no division is as stacked and vivid as WW. Rory, T-Wood, Hector... there are countless good contenders for the belt. Why should Robbie leapfrog them. He already had his chance.
