I'm on Pettis at -132. Diaz was impressive against Mcgregor, but Diaz had a big advantage on the round and much better cardio than Connor, Pettis is strong on the ground and he has good cardio. Pettis's winning percentage is 50% his last 10 fights but he's fought better strikers than Diaz, fighting Halloway, Poirier, Ferguson. Diaz hasn't fought for 3 years and he's doesn't have strong power as a striker, Pettis is the better kicker and he should be able to matchup with Diaz on the ground.
