The current generation of young boxers has made a tremendous impact on the sport over the past few years.
Look no further than the now two-time No. 1 fighter in ESPN's top 25 boxers under 25, Teofimo Lopez. His victory over Vasiliy Lomachenko in October 2020 turned the lightweight division upside down. Lopez's mandatory title defense against George Kambosos Jr. has been delayed multiple times, but should finally happen soon. In the meantime, he's considered the undisputed champion at 135 pounds, having won the WBA, WBO and IBF titles, plus the WBC "franchise" belt, and between the division he currently rules over, and the weights just above and below him, fighters at or around the age of 25 appear ready to take over.
