Canelo age was definitively an X factor because of his youth but a young mosley would have won. He was faster and more explosive than he is now.

Young Mosley would have pulled a decision but young Mosley was on steroids.

Still; if both were clean i would still put my money on Mosley in his youth.

Mosley was way past his prime when they fought. Prime Mosley would have beaten Alvarez, and would probably have beaten Mayweather too.

Yes

Maybe THE factor.

Yes he was just too old.
