Is Roach to blame for Kahn's downfall? Amir Kahn has all the talent in the world, speed, athleticism etc. Every fight he goes in to fight but has NO ring intelligence or DEFENCE. Roach had done a lot for Kahn but does Roach teach defence, angles or just how to punch fast? Look at Pacman, the same, awesome offensive fighter but ZERO DEFENCE. Kahn could have easily outboxed Peterson and Garcia but is TOO offensive - he doesn't haven't to be Mayweather but needs a defence and to fight smart.
