This Saturday's UFC 127 main event between BJ Penn and Jon Fitch will answer a major question in fight fans minds.
Is the old BJ here to stay?
With his quick knockout over Matt Hughes, fans want to know whether Penn is the same fighter that once challenged Georges St. Pierre at UFC 58, or the fighter that got his you-know-what handed to him at UFC 94 to St. Pierre. And though Penn has been written off as a contender outside of the lightweight and welterweight divisions, there are still some that believe that Penn continues to show a glimmer of his youth when Penn would've been able to easily compete with foes such as St. Pierre.
His fight with Fitch will be a good indicator of that, but it will not solely provide dispute of to whether or not Penn is still amongst the elite in the world outside of the welterweight division. Only a fight with middleweight great Anderson Silva would prove worthy of that distinction, and yet it is likely a fight never to happen because of the two fighter's differential in weight.
But think back to the time where Royce Gracie fought men twice his size, and arguably twice his match in strength. If that were still prudent today, would Penn have a chance against Silva? Would he be just the man to take out the consensus P4P greatest fighter in the world today?
Maybe not, but here's five reasons why he's better equipped to do it than St. Pierre.
