20+ years ago that would have been a no-brainer but nowadays they always sell the naming rights and it changes every 5 years or so. I'd settle for something like "The ______ Gordie Howe Arena" or whatever. That way they still get to attach their name and get credit for showing some class to a legend.
Maybe they will sell the naming rights to individual gates and arena sections instead, like they did with Lambeau Field.
