"the diesal" physicaly has what it takes, even technique wise but he makes os many stupid decisions in his fights thats cause him to lose.
in his fight with diego he tried to beat diego to the punch with a huge looping shot cuz he probably didnt even think diego would hit him once standing, he ended up getting hit himself right on the button, then what does he do?
he still rocked so he tries to standup with diego running at him, on his feet just in time to eat a huge knee.
he could have saved himself twice in that fight, 2 bad choices caused him too lose. diego capitalized on those mistakes.
