But in boxing, one night is all it takes for things to change in a major way. Last Saturday in Las Vegas, Marcos Maidana gave the pound-for-pound king his toughest fight in over a decade, earning a draw on one judge's card.
Maidana became the rightful heir to Luis Firpo's old nickname, "The Wild Bull of the Pampas." He had great success neutralizing Mayweather's famed counterpunching with his erratic aggression and consistently muscled the undefeated superstar against the ropes.
Mayweather came away with a disputed majority decision, but the rematch had all but been agreed to on camera before either man had left the ring following the fight. So that fight needs to get made, immediately.
Fans will still want to see Mayweather and Pacquiao square off. But Mayweather has unfinished business first with Maidana.
Boxing thrives or flounders based on the quality of fights getting made. If Mayweather-Maidana II happens this fall and half of the rest the list gets made as well, 2014 will go down as another terrific year for the sport.
