He seemed pretty confident in his cardio and being able to make it 12 rounds leading up to the fight with the interviews i saw i dont think its an endurance issue i think its energy utilization, when only 26% of your punches are landing its a problem he was investing alot of energy in the first 3-4 rounds (maybe he honestly thought he could knock him out in 4 why he didn't try to conserve) he should know Mayweather sits back for those first 3-4 and feels out opponents should of conserved till the later rounds when Mayweather starts to open up more and throw more punches and try to counter like he does very well. But that's just me i'm no professional just an enthusiast xd i also gave connor 4 rounds but oh well
