Khan ofcourse is the far better name and has fought far better names but as we know names meaning nothing and who you fight mean nothing its the fight that matters How you see this fight going?
Spence ruins him in 2 to 3 rounds perhaps quicker. Khan doesn't have the strength, power or ability to keep Spence off him.
Khan is 6-0 going into the 7th and then knocks himself out because he overheard a conversation about corruption.
