I know it's wrong. But more accurately, I think it's an argument based off a false premise. Cause literally every player in the league is product of their environment. Every player on this planet plays within a 5 man unit, there will be contributions of course from who they surrounded by and that's the truth for everyone. But this ridiculous notion of the McD effect only gets applied to anyone that plays on the Oilers cause no one else has a McD. But just cause McD is the best help around, doesn't mean no one else gets help either.
Also, I've seen McD injured and I can see what Drai does away from him. He can carry the team all by himself too you know and has proven that many times in the past. Even in games where McD is healthy but he isn't playing well that night, which happened alot in his early years, especially his first playoff run, I saw Drai carrying the team as the defacto best player.
I don't blame anyone if they can't see it though. I've watched every single minute of McD and Drai's careers, to come to these conclusions.
