it doesn't really matter if shakur moves perfectly for all 12 rounds. you can't run for your life for 36 minutes and still land enough shots to win a fight. you have to be faster than tank or way bigger and neither of those things exist at 135 right now. isaac cruz had the right idea offensively and im sure he's thankful his chin is as strong as it is, but he got beat clearly.
the only way to beat tank right now is to meet him in the middle, try to back HIM up, and smother his punches. running around the ring for 12 rounds waiting to get KO'd ain't beating him.
