Surviving Maidana's late rally.

Nah I think Khan's win over Algieri is better than Maidana. At the time Maidana was interim level whose best fight/win was against the then-hot prospect Victor Ortiz. Algieri was coming off a win over red hot Ruslan Provolone and winning a full title and losing to ATG Manny Pacquiao. If you measure those two fighters at the time Khan fought them I just can't see how Maidana was a better win

a fighter coming off a pillar to post beating with 6 KDs in the process in probably the worst scorecards differencial ever from a past prime manny is a better win?
I thought coming off a loss alone disqualifies that let alone in the manner that he did.
There's a bigger chance Maidana that Khan fought would whoop that Algieri as well.

Khan is a better fighter at 140 than he was at 147.
