This happens at every level of the game in just about every physical sport. They're two competitive players who are frustrated with the team's recent play, and things boiled over in a battle drill. It happens, and Kane, Falk, and Housley have not only said that it is nothing but said that maybe the team needs more of that fight. People are only making this a big deal because it is Evander Kane.
And he's on the trade block because he's a pending UFA, not because he's being toxic in the room. There have been no indications of that in Buffalo.
Then why dont they resign him he is a 25/30 goal scorer 50/60pt power forward. If he is so great and there is nothing wrong why dont you guys keep him?
