I'm not missing anything, you saying Crosby was nothing more then a 'nice addition' to the Pens?. Rookie year he's 6th in scoring with 39 goals and 63 assists, second year he tops the scoring charts with 120 points and also captures the Art Ross (youngest in history if I recall)
So can one person make a difference? I'm pretty sure Crosby proved that. Do I think there's one player that's going to help the Leafs like Syd helped the Pens? No, that's a once in a lifetime deal they got but it sure won't hurt if they pick high in the draft and get some young talent.
