All things like that are subjective and Bolt, Ali and Nicklaus all have great arguments to be the greatest sportsman , along with Federer. I wouldnt want to pick one to be honest. Daley Thompson and Tiger Woods are not in the same category - for different reasons, in fact I'd put Jess Ennis-Hill above Thompson in their field.
