The individual who ranked Gretzky number six and remains a consistent anomaly with respect to the rankings of Canadiens' players advances an agenda laid bare for all to see. If you don't conclude the obvious in this situation, there is nothing additional I can add to convince you otherwise. It's not a Francophone thing, per se. It's a generational and team-focused bias, in combination with the fundamental misunderstanding that defensive responsibility can be coached and instilled in most players. Offensive ability, however, cannot be instilled or coached. I think it's a general consensus that either you possess that ability or you don't by the time you reach the professional ranks, with rare exception.
For the record, I do agree with the many perspectives that feel Gretzky deserves to be ranked lower than number one. Ranking him at number six is suggestive of intellectual dishonesty or thinking you are the astutest person in the room.
