New studies linking football to brain disease. Still no testing for human growth hormone. The specter of other purported performance-enhancing products -- deer-antler spray, anyone? -- being peddled to players.
• A pay-for-pain bounty scandal. A lockout of officials resolved only after a ludicrous game-ending call. Zero minority hires for 15 coach or general manager openings.
• And yet the league is as popular as ever.
• Advertisers paid nearly $4 million per 30-second television commercial for the right to reach the 100 million or so Americans expected to tune in to Sunday's Super Bowl between the AFC champion Baltimore Ravens and NFC champion San Francisco 49ers. Eleven of the 12 most-watched TV programs during the last 2½ years were NFL postseason games, according to the league.

That's why I say my wife is always messing with me when I have outbursts, saying, 'You've been hit too many times upside the head.'"
• Montgomery laughed for a moment. Then he rubbed his forehead and continued talking, mentioning former teammate and friend Andre Waters and opponent Dave Duerson. Both committed suicide; researchers studied their brain tissue and found signs of chronic traumatic encephalopathy, or CTE, a degenerative disease also found in boxers and often linked with repeated blows to the head. Former star linebacker Junior Seau, who shot himself in May, also was found to have CTE. Baltimore's starting center on Sunday, Matt Birk, has pledged to donate his brain for study when he dies.
