I don't see a way back for Khan at the top

I felt at one point he was at the top of the 140 pound division, when Bradley ducked him.

He did duck him at the time, no doubt about it. He was unsure he could beat Khan. Even though he probably could have beat Khan comfortably, but he was definitely unsure of his abilities.

When Khan lost to Lamont Peterson, he came out to the public again saying he would beat Khan easily.

I think he was the top dog above Bradley at one point. It's arguable, but i felt he was the top dog around that time. Even though both guys resumes are arguable, and you could say Bradley fought the better opposition.

Even though it's arguable.

I think his dream of being the best in the sport is over. He can go on and fight Peterson again, and perhaps redeem himself to a certain extent. He could go on then to fight Garcia. Or fight Garcia first, or vice versa. There's many fighters in that division who may throw a spanner in the works by the time he comes back to be a force.

There will always be question marks next to him, though. I think his fights will always be edge of your seat action. Which makes his fights exciting but i honestly see no way of him being dominant as he once was, or was percieved when he was beating Kotelnik, Malignaggi,...etc... Some boogeyman will come along and give him trouble everytime.

And i think Floyd Mayweather Sr would not help him at all. Or Roger Mayweather. Hatton didn't improve at all. His style is not changeable imo. He can uses a highguard and pace himself better. Not go toe to toe with punchers, but he will always be hit.

I mean could you imagine Khan using a Philly Shell Defense ala Floyd or like James Toney. He couldn't train him that way as he would get knocked out instantly.
