NFL.com has an impressive article of stats about the Jaguars. My "favorites":
"Blaine Gabbert is 5-19 as a starting quarterback, accounting for 21 total touchdowns. As a rookie in 2011, Gabbert started 14 games and had 12 pass TDs, while last season he started 10 games and threw nine touchdowns. The last quarterback taken in the top 10 to account for fewer total TDs than starts in each of his first two seasons was the Bengals' Akili Smith, whose NFL career lasted only four seasons."
