If these featherweights can dish out this much punishment to a regular guy (concussions, emergency dental work needed, popping eyeballs out of your skull), how come they don't do any of this in the ring against other featherweights?
Because they're fighting other trained fighters who have spent their entire lives devoted to learning how not to be punched, and how to take a punch in the event one lands. Boxers very rarely take clean shots; everyone on this forum would be taking a clean jab straight to the nose if we tried taking on a fighter. If he was in a particularly bad mood, it would probably be to the throat and there would be a whole lot of time to flash through memories on your way to the hospital.Weight and size play a difference when the person is:
1.) Physically fit enough to last more than 20 seconds in a fight; most people think of themselves as uber-studs that can fight indefinitely when need be. The average Joe on the street would be taxed in a matter of seconds.
2.) Fast enough in terms of speed and reaction to avoid and land punches; pretty much a given that nobody here is. It's very easy to say, "Well I'd hit or grab him and since I weigh so much more if would do damage". You're not taking into account that this guy is going to be virtually telepathic to your eyes, he's going to be moving to defend or attack the exact second you make a move.
3.) Is built enough and can endure enough to take a
lot of damage.
4.) Has the ability to get out of the way once the flurry of punches start coming for their head; we're taking punch after punch in rapid succession at a speed you've probably never seen.
If you had all of those things, you might stand a chance. Then again, if you had all of those things you'd probably be a professional boxer in the first place. Weight and strength mean almost nothing if you have no idea how to use it.
We're seriously talking about a beating of unimaginable proportion. It'd be like Looney Toons.
