Isn't the whole idea of professional sport to find out who is the best individual/team of a particular sport?
So isn't it just human nature to speculate as to the 'best of the best' of those individuals/teams.
There is no right or wrong answer, it's just a personal opinion of people who follow a particular sport as to who they consider to be the greatest exponent of that sport.
Gee, give us a break, it's bad enough already with the 'thought police' and the politically correct brigade telling us what we can and can't say and do, at least let us keep and debate our own opinions!
