From a guy who watches them several times a year, their problems are the QB's and coaching staff. The WR's aren't special, but they are about average. The line and backs are good, and so is the defense. With their heavy emphasis on the running game though, Jacksonville doesn't have all that many possessions, and the QB's are simply not efficient enough to win consistently. Also, their coaching causes problems because Del Rio lets his players run wild. I don't know how many times I've seen the Jaguars lose games because of 15 yard penalties at the worst time because they can't control their emotions. He also doesn't have the team ready to play every week, which is how the Jaguars can beat Dallas, Pittsburgh, Philadelpia, Giants and Indianapolis and yet lose to Washington, Houston twice, and Buffalo.
