You don't knock Kat's out with one punch unless his resitence is totally shot which it isn't IMO. It will take a accumulation of shots and a finishing volley to get him out of there before the final bell. It's all about how Mitchell goes about his work...will he sit on his shots and rip hooks to body and meet fire with fire or will he go onto back foot and counterpunch? Kat's does look old facially when he arrived here (also jetlag) and his face looks war torn so cuts will open and from there he may be able to land some more hurtful shots. My Final Point is .....WAR LADS.....WAR!!!!!!!!!!!!!!!!!!!!!!
