I don't think it's about learning now for Khan, I think it's about making as much money as they can. A win against Alexander at welter makes him a remotely credible dance partner for Floyd and that's what this is all about. Khan's career at world level is basically over. Garcia or Matthysse would flatten him at 140 so Khan and his promoters are just looking to bullshit him into a Floyd fight and then sail off into the sunset.
