6. Steve McNair
Steve McNair probably never got the full recognition he deserved, as far as how good a quarterback he was, because he didn’t really put up the gaudy statistics of some of his peers, and because he didn’t play for a “spotlight” franchise. But in McNair’s first seven seasons as the starting quarterback of the Tennessee franchise (they were still called the Oilers for the first two years before their named changed to the Titans), his team only had one losing season. Tennessee lost twice in the divisional playoffs, and once in the AFC championship game between 2000 and 2003. But McNair’s closest shot at winning the Super Bowl, of course, came when the then St. Louis Rams came from behind to beat McNair and the Titans in Super Bowl XXXIV.
