Here's a McGregor vs Diaz 2 video. McGregor gasses out again at the same round and almost the same time as the first fight.

Yup....And, Alvarez is going to lean on McGregor much more than Diaz had, which is going to gas him even further. The way I look at it is that McGregor has to go for the earlier win which means exerting more energy in the first few rounds. If McGregor doesn't get an early finish, then the fight will belong to Alvarez. It all depends on the chin of Eddie Alvarez in the first few rounds.
