Keith Tkachuk understands that Thrashers teammates Ilya Kovalchuk and Marian Hossa are going to get roughed up when they take the ice. Hockey is a tough game and for a team to be successful, it has to be played that way. Against opponents of similar stature, he would do the same. Only far too often this season, Tkachuk believes, tough play has given way to dirty play. And with a spate of recent ugly incidents in mind, the veteran power forward feels his fellow players need to be a little more considerate toward their opponents.
