premise: National Hockey League commissioner Gary Bettman is looking at realigning the league's divisions and altering its schedule makeup, The Sports Network of Canada reported on its website Friday.
  Citing unnamed sources, TSN said the overhaul being considered would see the six current divisions reduced to four with each division having seven or eight teams rather than five.
  Six club executives, one from each current division, met with Bettman in New York earlier this week to discuss the matter and take information to other clubs in their division for feedback.
  Twenty of 30 teams would have to back such a move in order to make it happen next season. That could happen at a board meeting during the NHL All-Star Game in Dallas next month.
   What is involved in the overhaul?
