it would have to be Roy jones Jr Vs Oscar De La Hoya if the fight happens i cant think of many other miss matches that are worse than this 1
are you talking overall? like... we can pick two fighters and who can come up with the biggest mismatch??? ooooor... mistmatches from the past? or what??? at any rate.. the biggest mismatches ive seen involving two big names was Mayweather vs Gatti and Mayweather vs Baldomir... also Oscar vs Campas oh wait... theres one coming up... Hoya vs Forbes. and i dont see why roy jones jr vs hoya would be any more of a mismatch then it was against tito... roy fights like a ***** and hoya has a good chin, is more active and is faster then tito.
Thai fighters make the worst mismatches. Somsak Sithchatchawal fought guys who had 0 career wins while he was a beltholder. Pong wasn't much better.
Hopkins against Hakkar. Now that was the definition of running. I think Hakkar was in the Olympics but it sure as hell wasn't for boxing!
It's gat to be Muhammad Ali against Chuck Wepner, the Bayonne Bleeder, in 1975 - 45 minutes of pure facial torture.
