Like Fernando Vargas, Hasim Rahman, John Ruiz, or a lot of other fighters. He's not mediocre, but not great. Sad thing is, some guys like Holyfield or Barrera have losses, but did things to be great later on. From here Khan will only decline.
This is how I see it too. The some losses he has will be very bad though since getting brutally knocked out is always a very real possibility with him
I agree people make a big deal about a loss to much, with saying crap like oh he got exposed, he has a glass jaw and all that sort of stuff, not everybody can be undefeated.
