Not sure what the purpose of this thread is 95% of boxers dramatically decline after a grueling fight at some point. Unless you mean decline after their first grueling fight... but then why Cotto listed when his first grueling fight was against Torres?
One of my favorite fighters Roy Jones Jnr. after the second Tarver fight was never the same. But I blame that in dropping 24 pounds after the Ruiz fight.

David Reid after Trinidad
Vassily Jirov after James Toney
Ancelino Freitas after Diego Corrales
Edison Miranda after Kelly Pavlik

Oscar won that rematch in my opinion against mosely but it is after that when he fought sturm which he lost, then hopkins, then he beat mayorga, and then lost to Mayweather.
