I dont think any amount of training will help. Conor is probably naturally around 170 pounds. When he cuts weight to get to 145 I would not be surprised if on fight day he is 165-170 pounds anyways. Unless he was fighting Diaz at 180-190 then I do not buy the gassing out excuse. Most 170 fighters are probably fighting at 190+ and they are naturally bigger / longer reach. Also I think his power can only transfer so far. Look at Pacquiao in boxing once he got to a certain point the knockouts stopped. Diaz was cut up, but the announcers said that he has so much scar tissue that he bleeds really easy. Plus Diaz did not seem to be rocked or in any trouble at all. Once he tagged Connor a couple times that was it. I think that 155 is Connor's max weight
