The Doc or the corner should have stopped the Guiterrez fight. If you dropped anything but avitene into that it would echo. Mares may have been made to look sharper than he was without having to worry about what was coming back at him, but he put his work together with some style, and looks ready to reset and go again for a place at the top table after that. Santa Cruz did what he had to and can't be blamed for a weird stoppage in a fight that he pretty much bossed.
