35-year old Steve McNair has decided to hang up the cleats.  He played in 6 games for the Ravens last season and he completed 133 of 205 passes (64.9%) for 1,113 yards with 2 TD passes and 4 interceptions (73.9 QB Rating).  McNair also carried the ball 10 times for 32 yards (3.2 ypc).  McNair finishes his NFL career having played in 164 games.  In those games, McNair completed 2,733 of 4,544 passes (60.1%) for 31,304 yards with 174 TD passes and 119 interceptions (82.8 QB Rating).  McNair also carried the ball 669 times for 3,590 yards (5.4 ypc) with 37 TD runs.  McNair will probably make it to the Hall of Fame but his play was slipping big time and he made the right choice to call it a career.
