Juan Manuel Marquez Promises to Fight Hard Against Pacquiao

Juan Manuel Marquez is making a promise that boxing fans will hope he lives up to, as the Mexican veteran is guaranteeing he will not turn in a Shane Mosley-like performance when he faces Manny Pacquiao for a third time on November 12:

"It will definitely not be like the Pacquiao-Shane Mosley fight where Mosley kept running. As best as I can, I am going to fight him toe-to-toe and give the people what they want."

This quote sort of reminds me of the scene in Tombstone where Wyatt Earp asks Doc Holliday, regarding a gunfight with Johnny Ringo, "I can't beat him, can I?" Doc says no. But Wyatt goes off to fight Ringo anyway, intending to do his best. Marquez says he feels he can match Pacquiao's power and speed, which I don't think many will assume he can, but this is why I don't hate the fight: I am utterly confident Marquez will live up to his promise and go out guns blazing if he is in fact going to lose, and my gut feeling still tells me he's going to know pretty quickly that the game has changed for him against Pacquiao, due mostly to the fact that Marquez has aged, great a fighter as he still is.

Marquez also still has his July 16 tune-up with Likar Ramos in Mexico, which shouldn't give him any trouble on paper, but I keep getting more and more worried that the unthinkable could happen (so I'm now about 0.8% worried), and then what does Pacquiao do on 11/12?
