This video is the perfect example of how skill beats strength, even with a size discrepancy this large.
The other factor in this match-up is the age between the fighters. As much as 16-year old guys want to believe they are the epitome of alpha males, they usually haven’t grown into their frames yet. As such, even the most highly skilled teenage fighters are going to be lankier and clumsier until they get a little older.
Take the kid in this video. He is a lanky, skinny 16-year old kid, but while his opponent spends his time on weights, he is spending his time on the mats.
