In a best-case scenario, the Rangers don't need Kane � they will have adopted Laviolette's system quickly, the pieces added in free agency will fall into place and all will be well by November.
Things don't usually work like that, though. And if Chris Drury decides, as he did at the deadline this past season, that the lineup is crying out for Kane, he'll move mountains to get it done, even though moving mountains in March didn't really work out.
And then Kane has to choose them. He might choose Edmonton or Colorado, or maybe Buffalo, depending on who can squeeze a modest cap hit in and which team Kane feels has the best chance to win. I have heard he really enjoyed his brief Rangers stint and would love a shot to show what he can do there when healthy, which he definitely was not in the spring.
