By Chris Williams: In the stock market, you got to know when to cash out otherwise you’ll end up losing your money. It’s the same way with fighters unfortunately. Cash cow fighter Manny Pacquiao is starting to show signs of aging, and was beaten in his last fight by Tim Bradley.

Pacquiao’s promoter Bob Arum has seemed in the past like someone not in a real hurry to make a huge money fight between Pacquiao and Floyd Mayweather Jr. for some reason. Perhaps Arum wasn’t ready to take a risk with his money fighter Pacquiao because the that good green cash was flowing in like waterfalls with Arum matching him up against his Top Rank stable fighters one after another.

I suppose if Arum had put Pacquiao in with Mayweather two years ago, Pacquiao would have been whipped and badly exposed by Floyd. The money that could have been made in a Mayweather-Pacquiao fight would have been huge no doubt. But Arum was still making big money just matching Pacquiao against his Top Rank stable fighters like Miguel Cotto, Antonio Margarito and Joshua Clottey.

Things have kind of gone to pieces now that Pacquiao was actually beaten by one of Arum’s stable fighters in Tim Bradley. It wasn’t an accident. Pacquiao simply is starting to age and he can’t seem to fight for three minutes of every round any more. He’s now a fighter that puts out a big effort at the ends of each round to try and win the round with seconds left. It’s all pretty classic for an aging lion.

The thing is Pacquiao isn’t someone that you can count on to beat even the Top Rank stable guys that Arum puts him in for in house club-like fights. Pacquiao could face either Bradley or Juan Manuel Marquez in rematches in November and there’s a very real possibility that Pacquiao will get beaten by either one of those guys.

Don’t get me wrong, Pacquiao is going to make some good clean cash against either one of those fighters, but that cash flow may dry up if he gets spanked again. For this reason, I think Arum needs to think very hard about cashing out with Pacquiao before the bottom drops out on him and he takes another loss or two. Pacquiao already arguably should have suffered a loss against Marquez last November, and that would make two losses in a row for the Filipino.

Arum could make big bank with Pacquiao if he just put him in with Mayweather now. That money isn’t going to be there if Pacquiao loses again in his next fight and that’s a real possibility. Another loss for Pacquiao and he’ll be lucky if he can get a 30-70 split with Mayweather. Besides that, Arum will have an awful time trying to persuade the boxing public to pay to see a Pacquiao-Mayweather fight if Pacquiao gets beaten this November by Bradley or Marquez. For this reason, I think Arum needs to really consider cashing out with Pacquiao while he still can.
