Khan is 22 years old we don't know yet how much he will improve.

Right now of course he shouldn't be thrown in with Marquez but who knows where we will be a year from now.

A couple years ago Barrera was ranked in the top 3 p4p, was vying for top dog with Pacquaio over the superfeatherweight division and any idea that Khan could have beat him would be met with hysterics.

Now he's just an old, little small man who Khan's promoter chose to get a legend on his record.

Isn't Marquez as old as Barrera? Isn't he as small?

A year from now Marquez will likely be coming to the end of his career and if Khan continues to improve and work on his defense with Freddie he could certainly be one of those that could potentially take over.

Who would have thought a couple years ago that Pacquaio would destroy De La Hoya, or that he would be the betting favourite going into a fight with Ricky Hatton?

On here people always talk about one fighter destroying another as if the gulf in class is colossal but it's just not the case.

Khan would still pose massive problems for anyone at lightweight, especially an aging Marquez who is at a clear natural size disadvantage.

Just because his punch resistence is supsect doesnt mean he's going to get blown away in 50 seconds every time he fights anyone world class.

If he can use his height, reach and speed to keep Marquez at bay and prevent him from getting off he could cause all manner of problems for Marquez a year or so from now.

Marquez isn't superman, he struggled with Jimrex Jaca and Chris John. His fights with Casamayor, Pacquaio, Barrera and Juan Diaz were all absolute wars with both Pacquaio and Barrera dropping him and Juan Diaz rocking him on occasion.

But you all assume that Khan would just lie down and be counted out after 50 seconds becuase he lost to Prescott in that manner?

Khan absolutely has the potential to beat Marquez. He has the all the physical and youth advantages, he has the speed and natural size.

If he improves under Freddie Roach then a year or so from now and he could be ready for the truly world class.

Although by then Marquez will doubtless be showing signs of slipping and even if Khan beats him he'd get no credit for it here anyways.
