I think the condition problem had to do with Trout being a much bigger man than Cotto is used to, and getting drained from having to carry his weight when they slugged it out on the inside and in the clinches. A lot of fighters (past and present) say how draining it is to tussle with a bigger guy.

Trout was the better man that night, plain and simple. He deserves respect for coming into a fight with a legend as a relative unknown and whipping ass.
