I dont know how much brock will be able to work on his fear of getting hit in the face in few months,cain couldnt finish kongo in his fight and landed 10 times more punches than he did in the brock fight.
Dos santos is a monster,everyone agrees he is the best striker in the heavyweight division,looks for the finish,head hunts,good cardio,and excllent take down defense.
i dont think brock will be champion anytime in at least 2 more years.
