Junior Dos Santos Vs Shane Carwin winner?

im giving it to carwin by TKO, but idk when because carwin has the ability to end the fight at any point in the fight because of his massive hands. im not saying junior cant either. We also have to see whos chin will hold out the longest because this will be a war. Speed vs. Power, also carwins conditioning will play a big factor here too. But all in all i think carwin is gonna catch junior like he caught lesnar but this time hes gonna finish it.
