Morales is one of my favorite fighters ever, but this is a bad move and just the type of decision that I was worried he'd make.

Morales is an ancient 30 years old, has been in so many wars I've lost track, and has drained his body over the years by killing himself to make the weight. Now he's moving up in weight to fight a slick boxer who is also the naturally bigger man.
It doesn't matter that Casamayor is 35, in boxing years he's younger than Morales.

I admire his neverending desire to be a world champion, but this is not a Bernard Hopkins-type situation. Hopkins was over 40 years old when he moved up to 175, but he had suffered very little punishment over the years and was in strong physical condition. And the Taylor losses he was coming off were plodding, technical fights.
People keep talking about Morales' "heart," and yes, it's a great quality, but while heart can help take a young fighter to a top, heart can also cause an old fighter to hang around far too long and suffer beatings that can affect the rest of his life.
