Hm do not agree entirety, MC is more skilled than those 2 combined. I think he could take them, altho it was good that Ant stept in
Skill has nothing to do with it. MC is of average build, both of those bozos are peak or near peak physical form.
MC himself said that he went for the guy's chin (Caleb) and hit it perfectly but it only made him stagger, not get him knocked out.
MC is actually not too far off from Dawe's physique, based on what Anthony said on rooster. But he's nowhere near capable of taking down Chad & Caleb without serious training in martial arts, not to mention building up his physique.
You have to understand that MC is an amateur fighter, even the trainer dude said so. Only advantage MC has over Caleb is kickboxing. Caleb's taller so he has more reach. He has a monster of a build so he's got great endurance and strength. MC can't beat that guy conventionally, have to think outside the box. (From a story perspective rather than gameplay.)
