OWINGS MILLS, Md. — Well over half the players on the Baltimore Ravens' 53-man roster have participated in at least one playoff game.

Only one of them, 36-year-old linebacker Ray Lewis, has a Super Bowl ring.

Several of the veterans on this team wonder if this could be their last chance to claim a championship. Center Matt Birk, who has played in a total of 12 playoff games with Baltimore and Minnesota, says, "This will probably be my best shot at it."

Safety Ed Reed has been named to the Pro Bowl eight times, but says winning a Super Bowl is far more important.

The Ravens (12-4) had a bye last week after winning the AFC North. They open their playoff run Sunday at home against Houston (11-6).
