Thaxton has masses of experience which is priceless, he would not be bullied by Khan i also think he would stop him late. Thaxton is a strong fighter and i think his rough tactics would scare the shit out of amir once he was in with jono. it's easy to ko people who are smaller than him and dont have the belief in themselves to beat him. Thaxton would have the right mental attitude with khan and that would count for a lot.
