I don't understand the argument here... Are you seriously saying that Kane is a better hockey player than Crosby, based on this one season? Like was mentioned, Crosby had one of the slowest starts of his career and still finished over a point per game. Your going to use career points per game as one of your arguments? Kane has 1.01 pts/g in the regular season and 0.98 pts/g in the playoffs. Crosby has 1.33 pts/g in the regular season and 1.14 pts/g in the playoffs. Crosby is also a much better all around player. The only edge I would give Kane over Crosby in their individual games is stick handling, everything else Crosby is far superior.
Sure Kane has three Cups to Crosby's one, but that's also a team stat, and Crosby very well could add another in a few weeks. Crosby also has two Olympic gold medals to Kane's one silver. But if you want to talk individual awards, it's not even close. Kane has won the Calder in 2008, Conn Smythe in 2013 and Art Ross this season. Crosby was the runner up to Ovechkin for the Calder in 2006, and has won Rocket Richard in 2010, Art Ross in 2007 / 2014, Lester B. Pearson in 2007 / 2013 / 2014, Hart in 2007 / 2014, Mark Messier in 2007 / 2010, among many other awards and accolades.
Crosby is regarded as THE best player in the world by most, Kane is top 5-10 by most... He would be outside of my top 5, possibly even 10, but that's my personal opinion...
