In a way your right, it's a Sports town. Detroit is a hockeytown, if you don't think so go to the Plymouth Ice arena and watch the Ontario Hockey League. Youth Hockey is huge in Detroit. In fairness, I do think there's a bit of Red Wing fatigue, because they are pretty much automatic for the Playoffs, so fans don't get as interested during regular season. Its kind of like talk to me in the second round. I also think the late start times on away games during the reg. season discourage fan interest here. The Wings play over 70% of their away games in a later time zone.
The other issue is Hockey is expensive, and the economy in the area is pretty poor. But the Detroit area is a huge sport town. We have Three sport talk radio stations. Also football is King everywhere, and the Tigers are one of the oldest franchises in pro sports with a ton of history. So with the Lions starting off so hot, and the Tigers in the playoffs, it's hard to watch three games at once. But I'd still wager that despite the greatness of Isaiah Thomas, Barry Sanders, or Verlander, the most popular Sports figure in town is still Steve Yzerman. But if Stafford becomes a legand, all bets are off.
