That's simply your opinion. Logic would dictate that if a forward spent more time in the offensive zone and less time in the neutral zone or his own zone, he would see an increase in points. Someone scoring 130-150 points a year would see a pretty strong increase in offensive numbers if they played a more offensive minded game.
Gretzky and Lemieux are two of the top 3 players of all time. Yzerman isn't even top 10. There is a reason for that. He never had the offensive skills in any point in his career that Lemieux and Gretz had in their primes. That isn't even arguable.
Lidstrom was a -2 and won the Norris. Next.
Nice snarky answer. For all the big offensive numbers Crosby puts up, he hasn't finished with more than a +20. In fact, when he won the Art Ross in '07 he finished with one of the lowest +/- totals in the history of the NHL for a recipient of that award. In '09 he had 103 points and was just a +3. Even the year he scored 109 points and led the league in goals, he finished with just a +15. Seems to me, if he's good defensively, with all the points he accumulates, shouldn't his +/- be much higher? Datsyuk was able to finish with a +41 in a year he scored 97 points. A +36 in a year when he got 87 points. Now comes the part where you say "plus minus doesn't matter", but those 20 seconds Crosby plays at the end of a penalty kill against a teams 2nd PP unit means more.
Also, if you don't want a snarky answer, don't act like just by watching Crosby a few times you know for a fact how often he plays in a certain situation. The NHL website has all that information right there.
Datsyuk has 3 Selke trophies, good for 2nd all time. Crosby hasn't even been close to a nomination.
Everyone knows that the Selke is a primarily reputation based award. The fact that Datsyuk has won it over players (Zetterberg included) who over the past few years have had greater defensive responsibilities (PK time is a huge reason why him winning 3 in a row is suspect to me) and defensive performance makes me wonder why people decide to use it as an indicator of who is truly the best defensive forward.
