If he can teach Khan how to spoil when he's out of position and use his feet more effectively, it'd be a perfect match.
Khan needs to go to 47 and scoop up that record of getting KTFO 3 times in 3 different weight divisions
They must have been reading my posts...:yep Seriously though, this would be a really good fit for Khan. If anyone can help with his flaws it'll be Hunter.
We must remember he's been with Ward since 13 so if he's to get Khan back up on his feet (no pun intended) he's going to need time and we can't expect miracle work. Khan has to put the work in which i'm sure he's willing to do but also accept his mentality needs to change. Virgil has had a extremely long time to make Ward into the fighter he is today, plus Ward has a very special mentality. Working with lesser or more fragile fighters will be a harder challenge for Virgil. That's what might motivate him for this job.
Apart from the obvious technical stuff he'll learn, I think the religious, calm respectful atmosphere that ward and hunter seem to radiate will do wonders for Khan's mentality and how he carries himself.
