Re: Boxings Greatest Trilogies
Loi/Ortiz and Loi/Perkins may deserve mention. Jimmy McLarnin had superb trilogies with both Barney Ross and Billy Petrolle. Tony Canzoneri was in decline when he boxed his trilogy with Lou Ambers, but in dropping Ambers twice to take the inaugural meeting, Tony executed one of the most masterful boxing displays I've ever viewed on tape.
There are too many classic trilogies to mention, but I wanted to go off the beaten path a little.
