No more than the NFL should for the Dallas Cowboys.
As I understand with the Stars, the Gund brothers, who owned the Golden Seals that became the Barons that merged with the Stars, wanted to move the team back to the Bay Area, but the league (gasp!) overrode this. Eventually they gave in and granted an expansion franchise to the Gunds, who got to take their half of the North Stars to create the San Jose Sharks. Then Norman Green came in and bought the team and everything looked to be good, with the North Stars making it to the finals in '91, but the Met Center was getting too old and they couldn't replace it, so they moved to Dallas.
What I never got was, why not the Target Center? I really wish the North Stars and Golden Gophers could have shared a rink. That would've been ideal, one huge Minnesota Hockey Center.
