What, you mean 7? Golovkin and Gonzalez have 17 a piece. Floyd, Manny, and Hopkins all have about 30 title fight victories. Leonard was a unified champ for 8 years. Benny in his prime. This content is protected Lew Tendler would be like Mikey Garcia level and Benny is completely dominant here. Can't find a lot of footage of Leonard besides the two Tendler fights. The McLarnin fight was way later during his comeback after he'd been retired six years and lost all his money in the stock market crash; so it's not exactly representative of the man in his prime.
Nothing you said disputes what I said. Lomachenko has more title fights than most people have in their career. he isn't all that inexperienced.
