If boxrec does not lie, his last smaller rival was bunema on 2008. His last 10 rivals had a combined record of 331-13-4, including 4 undefeated fighters, all 10 guys younger than him. Just compare that numbers with other P4P guys and think about it. Sergio is just getting older. He will get KTFO early, as was Pacquiao, as will be Floyd if fights anyone with a pulse... father time does not forgive and this generation is just done. The exception is BHop, but he signed a contract in the Crossroads...
Overrated and getting old oh wait lets all pretend the middleweight divisions been really good in Martinez's reign.
