I would prefer Indianapolis and Milwaukee to Cincinnati and Omaha.
Atlanta, Houston, KC, Quebec and SLC are fine though.
I want the NHL to do a five-division alignment as follows with expansion teams:
Central: Chicago, Columbus, Detroit, Indianapolis, Kansas City, Milwaukee, Minnesota, St. Louis
East: Boston, Buffalo, New Jersey, NY Islanders, NY Rangers, Philadelphia, Pittsburgh, Washington
North: Calgary, Edmonton, Montreal, Ottawa, Quebec, Toronto, Vancouver, Winnipeg
South: Atlanta, Carolina, Dallas, Florida, Houston, Nashville, New Orleans, Tampa Bay
West: Anaheim, Arizona, Colorado, Los Angeles, San Jose, Seattle, Utah, Vegas
The regular season schedule format would see each team play 50 division games, 7 against 6 opponents and 8 against the other one. Division matchups that get played 8 times would rotate every year. All non-division games get played once, alternating home ice every year.
For the playoffs, the top four teams in each division qualify. The American teams would stage their playoffs until each division has crowned a playoff champion. At that point the North Division starts their playoffs to determine one bid in the Stanley Cup Finals, while the remaining American teams are re-seeded and play for the other spot in the Stanley Cup Finals.
