Canelo Alvarez, the 21 year-old Mexican, will take on the toughest test of his career, in Shane Mosley, on the undercard of the May 5 Floyd Mayweather-Miguel Cotto fight in Las Vegas. Or..maybe you don't think so. You saw how Mosley looked in his last outing, a UD12 loss to Manny Pacquiao last May. He showed some defensive chops, in steering clear of punishment, but drew scorn for what many termed a mail-it-in performance. He is 40, turns 41 in September, and past his prime. Could he prove the world wrong, and give the 39-0 Canelo, the WBC junior middleweight champion, a tutorial? Or is the 46-7-1 Mosley just a name now, just a scalp to add to the resume? What do you think, TSS Universe?
