Duckweather reigns supreme at the top of that list. The rest of the list you can fill with the cheaters on the TMT stable.
Woo...slow down there. Avoid young gun? Does Lacy and MK ring a bell. What about a Prime, undefeated Viet? The same Viet that would most likely fight Froch and Ward to a standstill. What other Young guns were there?
A cherrypicker dosen't go overseas and beat 2 ATG american fighters in their home country. This kind of performance is insane IMO.
Some would argue he waited for them to get older, but Hopkins to this day is still top level. Roy Jones though was not really P4P level at the time.
The only significant fighters that Mayweather has fought since Hatton were the last two, Alvarez and Maidana. Marquez, Mosley, Cotto, Ortiz, and Guerrero were unnecessary and a complete waste of effort.
Minus Guerrero whom he should've never faced, those four other fights should have taken place years back when everybody was still in their primes. Mayweather gained no respect form fans and boxing pundits in those five fights. Maidana and Alvarez OTOH were legit, solid competitors.
Actually let me take that back: Mayweather should've never fought Marquez to begin with, even in the latter's prime.
You know I wouldnt call Calz a pure in your face cherry picker but he was superbly managed and did leave a huge void in my personal opinion. Maybe the older I get the more I will grow to respect his career or degrade it....who knows. The verdict is still out though he's retired so it is what it is at this point.
