We saw Conor Mcgregor's boxing skills when he took on the GOAT Mayweather and lasted 10 rounds (winning the first few) Now imagine Conor trained stricly boxing from a young age. No grappling. No kicks or elbows or take downs. Just pure boxing and striking. How far would he have gone in boxing? Pro contender? World champion? Lineal champion? ATG? Ali level?
