Technical Overview
Oscar Collazo’s boxing style is built around maintaining excellent control over his center of gravity, which helps him recover quickly when he’s behind in a fight. This stability allows him to land powerful punches at any time, making him dangerous for his opponents. His natural power is a huge asset, but it’s his technical skill and understanding of power punching that truly make him a threat.
Collazo often uses explosive movement off his back leg to close the distance and throw hard punches. However, this requires awareness, as after he throws a counterpunch or an offensive shot, his hand sometimes drops, leaving him open to counters. His punches can be a bit wide, but he counters this with strong shoulder rotation, which helps protect his face and soften incoming punches.
Though he sometimes fights in a straight line, Collazo’s physical abilities and power allow him to get away with it. His athleticism and strength let him execute this style effectively, making him a tough fighter to deal with. Additionally, he has the ability to box inside and focus on bodywork, especially against larger opponents, making him even more versatile in the ring.
