The thing that sold me on him that I've said ad nauseam on these boards was his supreme adaptability. He could be the fancy sniper playing up-tempo, open-cycle hockey when playing with a guy like Joe Sakic, and then turn it around and play low along the boards and get the greasy goals in the slot when alongside Paul Stastny, or a combination of the two with Peter Forsberg. Hell, he and Alex Tanguay played an entire game with Travis effing Brigley at center and it somehow worked. He doesn't get enough credit for being as complete a player as he was.
The one and only time I ever remember him looking out of sorts on the ice was when they put him on the point of the power play. You could tell he got nervous about turning it over and overhandled the puck. Thankfully that experiment ended quickly.
A shame he was only captain for one season but I think the decision to relinquish the C was his choice.
