Oh Yeah, well remembered, I forgot about that. Khan goes through trainers like errr pairs of trainers LOL
I remember him in both, as well as Diggstown, Ace Ventura. Also remember him fighting some big names from the 70's/80's Norton, Shavers, Holmes.
I think Goosen is a good trainer for the most part. He doesn't try to fit fighters into his mold, rather he works with their best attributes. Khan's best attributes are his jab and boxing ability. Besides, it's not like Amir would listen to detailed advice anyway.
