One covets chaos while the other craves a quiet life.
But together Ricardo Mayorga and Manny Pacquaio form an unlikely alliance charged with leading the next generation of boxing superstars.
Both men began to scale the sport?s summit from the humblest of origins and have emerged as two of the few heroes of the modern era.
In dispatching Marco Antonio Barrera in 11 thrilling rounds in Texas earlier this month, Filipino Pacquaio inherited the great Mexican?s position as the featherweight standard-bearer.
Meanwhile Nicaragua?s Mayorga blazed to prominence with back-to-back wins over former undisputed welterweight champion Vernon Forrest and is now targeting a mega-fight with Oscar De La Hoya.
