Hope not, I have a feeling he will make necessary adjustments and imoprove - I know he can;t strengthen his chin, but technical imoprovements to his skilss can be made to compensate...
Fighting like a professional would be a start :deal In the amateurs you obviously have a headguard, and the referee gives you a ten count on your feet if you are anything like hurt. Obviously in the pro's the referee allows the opponent to..... A. Knock you down B. To finish you off Khan didn't seem to realise that the best thing to do having been KD'd with 30s gone in a round is either...... A. Get on your bike B. Cover up like **** C. Hold on for dear life (even lose a point if necessary) He has a criminal tendency to drop his hands whilst throwing a punch - now against shot fighters with slow reflexes this won't be an issue (as proven mny times with many fighters) however against bangers or even moderate punchers you are going to be in serious trouble. A lesson in inside fighting would also help. I think Freddie Roach will be great, and won't allow any of the stupid 'outside influences' that appear to carry so much say at the moment - all these managers, advisors etc.
Feel a bit for Martin Gethin - doesn't always receive much credit or recognition. I think he is a decent opponent for Khan in the circumstances.
