One of the greatest fighters of the past 30 years is set to return to the ring on July 19 when Manny Pacquiao ends his retirement to face Mario Barrios. Pacquiao will be looking to add to his legendary resume by picking up another championship as Barrios' WBC welterweight title will be on the line.

Age-related concerns aside, Manny Pacquiao is going to have to overcome a significant reach advantage if he has a chance of beating Barrios. While Pacquiao could feasibly have a power advantage, he's almost certainly going to need to absorb punches from Barrios (especially jabs) to get within range.
