Brian Burke is struggling to come to grips with the evolution of hockey. Long a proponent of rough-and-tumble hockey, Burke now presides over a Maple Leafs team that is built largely on speed and skill. The sport has trended in that direction since the lockout and it has come with a few other developments Burke finds troubling. "If you want a game where guys can cheap-shot people and not face retribution, I'm not sure that's a healthy evolution," he said. "The speed of the game, I love how the game's evolved in terms of how it's played. But you're seeing where there is no accountability." According to numbers provided by the NHL, fighting is down significantly this season. Through play Wednesday, there was an average of 0.8 fighting majors per game compared with 1.2 at the same point last year.
