Mosleys stamina was always overrated. He was blowing after a few rounds against Cotto and struggled in the middle rounds, Floyd didn't give Mosley hope late on in the fight like Cotto did with his inferior defense and Mosley had effectively given up.

Floyd's a special fighter, he has the same balance and composure going into the 12fth than the first, actually he gains it through the fight as he warms up.
