"There's obviously a lot of good teams in all the divisions, but I think it will be cool to play St. Louis a little bit more, being from there," said Keller, who grew up in Chesterfield, Missouri, a suburb of St. Louis, and leads the Coyotes with eight goals and 18 points.

Seattle became the League's 32nd team after the NHL's Board of Governors voted unanimously to approve the expansion application from the NHL Seattle group.
The Board of Governors also approved a realignment plan that will shift the Coyotes from the Pacific Division to the Central, joining the Chicago Blackhawks, Colorado Avalanche, Dallas Stars, Minnesota Wild, Nashville Predators, St. Louis Blues and Winnipeg Jets, giving the NHL four divisions with eight teams each; the Central now currently has seven teams.
Seattle will be in the Pacific, joining the Anaheim Ducks, Calgary Flames, Edmonton Oilers, Los Angeles Kings, San Jose Sharks, Vancouver Canucks and Vegas Golden Knights.
"It's down the road a little bit," Keller, who can become a restricted free agent after next season, said after the Coyotes morning skate prior to their game against the Los Angeles Kings at Staples Center (10:30 p.m. ET; FS-W, FS-A PLUS, NHL.TV). "We're focused right now about this season, and when the time comes I'm sure we'll have a rivalry with each and every team [because we'll] play them so much."
