If neither of them had headgear on in the first fight, then Logan would have gotten blitzed.
- He had a more physical presence, landing more heavy punches than KSI
- KSI received more warnings from the referee (for illegal low-ducking)
The difference in reach should be placed in the equation as well; for example, Campbell still able to give Lomachenko a little bit problem, even though heavily outclassed.
Anyway, they are both a buffoon, so this fight shouldn't be taken too seriously.
Well the first fight wasn't that bad. Logan Paul has experience as a fighter and knows how to train, stay dedicated etc. KSI, however, played FIFA on Youtube for years, and pretty much only started working out to prepare for the Joe Weller fight back in 2016?
In their first fight, Logan Paul simply lacked stamina. Technically he was far superior. So with only a single thing to improve (stamina) he should definitely be able to beat KSI next time. To catch up to Logan Paul, KSI would need to improve his technique, which definitely isn't as simple.
No headgear = TKO at the very least.
