Really? If we assume those players are anywhere near their prime, I think they would win the SC most years... and pretty easily too. I might move Poulin up a line and White down a line, and maybe try to find space for Rene Robert, but really they're pretty solid.
I don't know how they'd stack up against "all-time" teams. The all-time French Canadian team could take 'em, but I think they might be able to take the all-time Dirty team from the other thread... provided they didn't get too injured.
BTW, as a person who got to see both the Courtnall's play, although they ended up with similar numbers, Geoff was way more of an dirty agitator that Russ was. Russ was an amazing skater and much more smooth on the ice. If he had finish to match the rest of his skills he'd have been in the HOF. Personally though, I liked Geoff better (when he was on my team). Nothing he'd like better than to punch a guy in the back of the head, draw a retaliation penalty, and then score on the ensuing power play.
