Truth is, it's a pick 'em fight. Zab is a gatekeeper so-to-speak, and if AQueerCon can get by him perhaps it is then time to seek out the best-of-the-best in the division.
Khan might not have much of a chin but he does have a high motor and he would work the hell out of Judah for 6th round on ... Judah doesn't have a chance and lived off of that Corey Spinks win for as long as he could. He's truly the most overrated fighter of all time ...
Why do you think that Khan hasn't tightened his defence enough? Since the presecott defeat he has barely been caught with anything. He still looks somewhat fragile under pressure but that is mainly because we know how poor his punch resistance is.
