First off I would like to commend Amir for staying active and fighting three times this year. I have said (on here) before that it can be done, and should fighters want to stay active they can fight 3-4 times a ear at the top level.
So commendations to Khan.
And his next opponent will be Peterson. Initally I was surprised that he decided to give Peterson a shot for the unified titles, but there is no doubting that Peterson is a top contender in the division these days.
But what does Khan get out of this fight? Well for me, a victory here would cemment his position as being at the top of the tree in this division.
But, could he have chosen a better opponent? I would say: YES.
The only top-notch fighter in the division who Khan has not beat yet (apart from Bradley who won't fight him) is Devon Alexander.
Rumours have been rife for a while now that Khan is considering moving up in weight, but before he does I think he should beat Alexander. Thjoguh Devon lost his title (and unbeaten record) against Bradley, he's still considered in the elite of theis division.
So Khan fighting Peterson, a good fight? Yes/ But not a great fight... And maybe after Khan disposes of Peterson (a late stoppage I'm saying) he could target and beat Alexander in the US.
Then maybe the move up? (It doesn't take a genius to work out that he has his eyes on Mayweather).
