As for Pat Miletich, he was a great fighter for the time, but somewhat boring. He got by on toughness, endurance, and by being a smart fighter. His competition was also marginal.
I loved watching Miletech fight guys like Chris Brennan, Townsend Saunders, Mikey Burnett, and John Alessio, but I'm not sure any of those guys could compete in the UFC today.
Saunders was a great wrestler, but (like many great wrestlers who try MMA) didn't like to get hit. He only fought two times, lost both fights, and left the sport.
Brennan was ahead of his time in mastering jujitsu, but he was smaller than Miletech (who also mastered jujitsu) and didn't have enough of a grappling or athletic advantage over Pat to compensate for being the smaller man.
Mikey Burnett was a tough Lion's den fighter who gave Pat all he could handle, but Mikey was never that much into fighting professionally and he soon left the sport.
John Alessio went on to have a long career in the sport, but he was always a marginal talent and he looked completely overmatched when up against Miletech.
