Though Kane would be a great addition to the team, I think we all learned with Neal that not every player is of the perfect fit. Meaning...we all do not know how he'll fit in in all faucets of the team on and off the ice. Kane has shown good and bad qualities.
One is; Can he handle being 3rd/4th fiddle on a team with players much more skilled than even he is?
Just to not be confused by that statement here are the three players I would say are better or at least equal to him.
Crosby and Malkin are no contest, but Letang is most likely equal or better then Kane. The reason I'd say Letang is better than Kane is for the fact he's that good from a harder position that is defence.
Personally, I think guys like his captain of his current team are the true perfect fit for this team, and Kane would be another ego that needs stroked. A Neal for Kane would have been a great swap had they went that way, but really they'd be just trading one ego for another. So while I say I'd like him on our team, he's not what I would say is the perfect fit. We need grounded players who'll compliment what we do already have and can ground them as well. Hornqvist is certainly that type. A great player who is not going to be so good that his ego needs put in check. If we could get a guy in his mid 20's the likes of Hornqvist with a little more size would be awesome.
The problem is who's out there fits that stero type who is or will be available?
