Ali Frazier MAB Morales Marquez Vazquez +1(the fourth doesn't count ) Gatti Ward Bowe Holyfield That's in order of my favourite. Funny thing almost all trilogies only have 2 great fights in them.
I had assumed "trilogy +" meant 3 or more, since the OP included at least two rivalries that had more than 3 contests.
On the basis 'Kid' Lewis and Jack Britton met 20 times one would think they must have fought at least 3 great fights among them. Well played with the quadrilogy by the way. But what is the name for 20 meetings?
Throw Patterson-Johansson into the mix. And that one had (at least in my opinion) 3 great action-packed fights. But the ones you listed tend to be my among my favorites (along with Ingo-Floyd), right down to your exclusion of Marquez-Vazquez 4, which I much prefer pretending never happened.
You would think so. But just to play devil's advocate, Ruiz and Holyfield could have met 100 times, and I'm not sure they would have 1 "great" fight among them.
For whatever reason the two that jumped out to me when I saw the OP, were Pac-JMM and SRR-Lamotta. But in my estimation, MAB-Morales and Bowe-Holyfield (which both happen to be "true" trilogies) are better rivalries than most of those originally mentioned.
I must've missed that the first time around, I was distracted by his spelling of TriOlogy. I don't disagree with you actually. Add in Marquez-Vazquez, Gatti-Ward and Huck-Afolabi to round out the top 5.
