It doesn't take a whole lot of explanation to justify saying that the turnover margin is an important stat in the NFL. Turnovers are most often game changing plays that can turn the momentum in favor for one team and causing turnovers is one of the best ways for over-matched teams to beat teams when they are underdogs.
That's not to say that the Jaguars are underdogs, but it is a testament to the importance of turnovers and how causing them defensively and avoiding them offensively is a huge factor in any game.
Through four games, the Jaguars have fumbled the ball eight times, the sixth most in the league. Luckily for them, seven of those fumbles have been recovered by the offense. However, defensively the Jaguars have forced just one fumble, tied for the league's worst with the Chargers. The sole fumble forced was when Drew Coleman sacked Matt Hasselbeck in week one against the Titans and forced the ball loose.
To get wins against some of the stronger teams in the league, the Jaguars will need to start forcing fumbles. Especially when they are underdogs later in the season against teams like the Ravens, Steelers, Texans, Chargers and Falcons.
