If Khan can bring that refined technique into the ring, he's going to look impressive against Molina... I have my reservations about Khan being able to avoid his careless tendencies in just a few months, but it is possible. If he fixes that, it'll go a long way in improving his chances against Garcia. If Virgil combines that with whatever Ward does for physical strength (and it works for him similar to or as it does for Ward) and he'll be #1 at 140 once again.
On a side note: Virgil Hunter is huge...
