One of the concerns behind a cold-weather Super Bowl is that more cold-weather cities will want to get in the Super Bowl hosting line. Daniel Snyder has already said Washington should host one.
Now Ravens head coach John Harbaugh thinks Baltimore should host one as well.
"You may be surprised to hear that. But I'm all for it, you know why? It means Baltimore might get one. So you put one in New York, then come on down to Baltimore and we'll have a Super Bowl. Maybe I'm speaking out of turn, but Baltimore built a stadium, put a lot of money into a brand new stadium. So you start bringing it up [north], I think we want one."
That's two cold-weather cities that want to host one. Don't expect these owners of teams in cold-weather cities to stop expressing interest in hosting a Super Bowl.
