Guerrero has been to hell and back with that situation with his wife, Weathering those shots showed you his will to win.
He can take punches but I don't believe for a moment when he said in the interview "I wasn't hurt at all." I think it was in the 7th round when he played hopscotch.
Guerrero came out in the 12th like a ****in monster. I couldnt believe what i was seeing, hurting Berto with two left hands in the last 5 seconds and trying to finish him after the bell. He knows he heard the bell, Berto is soft for not responding back after 3 unanswered punches but i dont blame him cuz The Ghost was trying to kill him and eat his soul, ****in a.....
He showed a lot of heart, but you can have all the heart and will to win to win in the world and your not going to take the shots Berto was throwing if you have a bad chin.
