Following the surprising release of QB David Garrard, the Jaguars have turned to eighth-year veteran Luke McCown, who started seven games in his first seven seasons — none since 2007 — to keep the seat warm until rookie Blaine Gabbert is ready to take the reins. The Jaguars always have liked McCown's ability, and he will have an opportunity to prove he can stay healthy and run the offense effectively, in addition to mentoring Gabbert. According to an AFC scout, McCown can "get you through 3-4 games, but he is not a guy who can carry you for a full season." McCown is a good athlete, but he won't beat opponents with his arm. Instead, defenses should know where to find him on every pass play — making short, high-percentage throws. The Jaguars didn't exactly do McCown any favors. He attempted only 18 passes in the preseason and received virtually no first-team reps during camp.
