Ryan Mallett takes an unfortunate Ravens' uniform number

OWINGS MILLS, Md. -- Ryan Mallett is trying to turn around his career, so you would think the Baltimore Ravens would have warned him about choosing No. 7 as his jersey number.

If there is a cursed number in the team's 20-year existence, this is surely the one. Here is a look at the four players who have worn No. 7 in the regular season:

Chris Redman: He chose the number because he was born on July 7, 1977 (7-7-77), but it didn't prove lucky for him. A third-round pick in 2000, Redman went 3-3 as a starter before being benched in favor of Jeff Blake. He later played five seasons as an Atlanta Falcons backup.

Kyle Boller: The first quarterback taken in the first round by the Ravens is still a sore subject in Baltimore for never living up to expectations. His inaccuracy, problems with reading defenses and penchant for fumbling without being hit led to a 20-22 record in five seasons in Baltimore. Many fans still hold a grudge against him for sabotaging the Ravens' championship aspirations at a time when they still had a dominant defense.

Billy Cundiff: Just when you thought nobody could be more despised than Boller, along came this journeyman kicker. His missed 32-yard field goal in the closing seconds of a 23-20 AFC Championship Game loss in New England will be remembered as one of the lowest points in franchise history. You would've thought the No. 7 would've been retired after fans burned it following that all-time playoff blunder.

Bryn Renner: He lasted only three days on the 53-man roster as the Ravens' backup quarterback last Sunday. Enough said.

Mallett wore No. 15 at Arkansas and during his stints in New England and Houston, but that number is taken in Baltimore by wide receiver Michael Campanaro. That led Mallett to choosing the unluckiest number in franchise history.
