It’s been an unprecedented year for the National Football League.

Thanks to a national recession, the year for some teams has been marked by television blackouts, empty suites and undersold stadiums.

But not for the Baltimore Ravens. It was a tight squeeze, said Ravens President Dick Cass, but the team sold its last suite the day before it hosted its first game. And despite raising ticket prices this year when many other teams did not — Cass called that one a “painful” decision — M&T Bank Stadium quickly sold out for the season, as it has since it opened in 1998.
