For Showtime, the answer is EASY. It's faarrrr and away Corrales-Castillo 1. For HBO, it's harder to select.
Good fight. Too many fights to name just one methinks. Hagler Hearns, Tito Vargas, Barrera Morales, Hagler Leonard
HAgler-Leonard !!!!! While it was a surprise to see Leonard be competitive with Hagler, and arguably winning it, and while it wasn't a bore, it was far from an action fight.
Hagler-Hearns is overrated. Best round 1 in history, but far from the best fight in history. Ugo might be onto something. Chavez-Taylor 1 is easily a top 5 all time HBO fight at the least. Holy-Bowe 1 is on the short list as well. In the last 15 years, let's not forget Pavlik-Taylor 1. That's a top 10 all time HBO fight, easily.
First round of Hagler/Hearns is apocalyptic, though Must've been insane to see it as a mature fan of the sport as it happened
Hearns must have the worst defense in history cuz Marv was punching under water in there and still landing.
