should there be a "no rematch" clause for Pac-JMM V??

If Marquez knocks out Pacquiao again, Manny will probably retire. If JMM wins or loses he probably probably retires. I think there is a good chance that this is the last fight for both men especially if JMM stops Manny again like I think he will.

No.The people that don't like rematches can just skip it. As long as these two great fighters keep having good to great fights I don't care if they fight 100 times. The main reason there will probably be a fifth fight is because lots of fans do want to see it and it will make lots of money for the fighters and the promoters. If there is little demand for a 6th fight then there won't be one. If there is a big demand for another fight then there might be one. To put a no rematch clause in the contract sounds ridiculous to me. If they have a fifth fight there could only be a sixth fight if both fighters agree to it. If both fighters want a sixth fight then what purpose would the clause in the contract serve? Would it be so the fans that don't want a 6th fight don't have to see it? There is an easier way. If you don't want to see a 6th fight then just don't buy it and don't watch it. These are pro fighters who want to make the best living they can. You can't tell them who to fight or how many times they are allowed to fight them. Robinson and LaMotta fought 6 times. All of them were great, exciting fights that were loved by boxing fans.

No rematch. Marquez wouldn't have gotten a rematch if Pac knocked him out. So **** that. Move on.
