Who beats who?

Can not but help to notice some posters penchant to solely equate the who beats who in their bold predictions of who will win a coming bout. Their simple reasoning is like if Fighter B won over C who won over A...knee jerk conclusion is that B will be it over A....and funny thing such claims that B is therefore greater than both A & C, or is now a member of the goat list etc., etc.... Many fighters have won over Ali...also true for others like leonard, duran, hearns, hagler....but most of these guys who won over the mentioned fighters were never really considered greater... why? the answers are more complex than the ingredients of any invented drug or imagined concoction mixed/soaked to oil laden sea water....with carcasses of dead birds, fishes and men....
