Well this fight will show us if it's time to call it quits or if he's still got it. I mean if he loses a wide ud or gets knocked out (unlikely) then he needs to retire, but if he wins or looses a close decision then he still got it in him. I don't remember the first vargas fight, but in the second vargas was like a robot didn't move at all, completely shot, can't believe he's getting in the ring again actually. The collazo fight didn't tell us much either since he won it rather easily, and I don't know if collazo was just over rated or if he really did mess up his hand in the 3rd like he said that it prevented him from performing to his best. Hopefully mosley still got it and this will turn out to be a great fight!
