The Jaguars have signed QB Cleo Lemon to a 3-year contract to replace Quinn Gray as David Garrard’s backup.  The 28-year old played in 9 games last season for the Dolphins and he completed 173 of 309 passes (56%) for 1,773 yards with 6 TD passes and 6 interceptions (71.0 QB Rating).  He also carried the ball 31 times for 102 yards (3.3 ypc) with 4 TD runs.  Lemon has now played in 13 games in his NFL career and he has completed 211 of 377 passes (56%) for 2,185 yards with 8 TD passes and 7 interceptions (72.2 QB Rating).  He also has carried the ball 34 times for 109 yards (3.2 ypc) with 4 TD runs.  Lemon is probably a slight upgrade on Gray as it’s hard to evaluate him based on his play with the Dolphins who were a pathetic football team.
