Derrick Mason was a model of consistency for most of his 15 seasons in the NFL.
Mason announced his retirement Monday as a member of the Baltimore Ravens. He entered the NFL with the Tennessee Oilers as a fourth-round pick in 1997 and joined the Ravens in 2005 and spent six seasons with the franchise.
"The piece of my body that I play with the most was still here in Baltimore," said Mason, who spent 10 seasons as a teammate of the late Steve McNair, first in Tennessee and then again with the Ravens in 2006 and '07.
He's Baltimore's all-time leader in receptions and receiving yards and general manager Ozzie Newsome said Monday that Mason did more for the Ravens than any other free agent addition.
Mason is the only player in the NFL to top 60 receptions every season between 2000 and 2010. He played in just two games last season with the Jets and Texans. Mason retires with 943 receptions for 12,061 yards and 66 touchdowns.
