3) Byron Leftwich: 24-20 record, 58.7 completion percentage, 51 touchdowns, 26 interceptions, 6.7 yards per attempt, 196.6 yards per game

Byron Leftwich essentially has the same number of starts under his belt as Blake Bortles but he has 13 more wins. That alone is enough to elevate him above Bortles and Henne even though his numbers aren’t as great.

Ranking fourth all-time for the franchise in passing yards (9042) and touchdowns (51) and ranking fifth all-time in yards per game (196.6), Leftwich was far from the most explosive passer the Jags have ever had.

But in essentially three full seasons as a starter, Leftwich delivered wins. He was a starter in one playoff game in which he posted a pedestrian 179 passing yards and threw an interception.

The biggest knock against Leftwich is that he wasn’t able to complete full seasons. He never started more than 14 games in a year and he was quickly exposed as keeping a better player lower on the depth chart. The short Lefwich experiment was largely in part because he was a first-round selection in the 2003 NFL Draft.
