Manny is a living legend but I always worry about fighters as they get older. He needs to know when to walk away, I don’t know why he doesn’t retire. He really should think about retiring if he beats Thurman which I believe he will.
A fighter is only good as his last fight. So if we are going to based on Manny last fight against Broner, he still has the skills and the passion to fight. I think he is more determined to really shut down Thurman on July 20. I don't like to say that Manny is taking this personally, but it looks like that way to me.
Manny has fought a lot of fighters who is really a big mouth, but I have a feeling that Thurman is really getting into his nerves and so he will let his hands do the talking.
As for the retirement, nobody can tell a fighter it's time to hang up the gloves, it's disrespectful, they love the sports that they are willing to give everything until they feel that they don't have it anymore.
Pacquiao knows that Thurman needs to talk trash, it's all part of the pre-fight build up.
With that said, even though I think Pacman will win, I don't think he has too many years left in the tank, he will probably retire after his next fight or two, hopefully he can challenge for some more titles before he goes though.
