Far too early to tell. Pointless at this stage even thinking it. He's a good fighter. Beating Maidana isnt beating Pac of Floyd. Some perspective required!!
I think so... with his skills and speed I think he will go on to big things... he could cement his place in the hall within 3 years imo
Arum and Roach could make some ones Grandmother become a hall of famer, so in time if they treat Khan the way they do Pac he has a good chance.
If he keeps training his ass off under Roach... Then yes... definately, he has the attributes and the heart. Time will tell though.
After his last fight I am 60% sure. I have no doubt over his dedication and heart. I still have doubts over his tactical attributes in the ring, he made the fight much harder than it needed to be, when he realised he could take a shot. Maindana was almost done and he got complacent, therefore the jury is still out over his next few fights tactically.
