If you compiled a list of all the ways in which the Jacksonville Jaguars have cheated other teams and the league in general over the years, it'd be few and far between.
In fact, according to YourTeamCheats.com, the Jaguars are at the bottom of the list with the fewest infractions of any team in the league. But that doesn't mean they're totally innocent.
There were only a few times the Jaguars were found outside the rules, and most of them weren't even the team as a whole but rather players like Marcus Stroud, T.J. Slaughter, and LaRoy Reynolds taking performance-enhancing drugs.
The best instance of "cheating" however was when the Jaguars grounds crew painted the arrows so that they pointed backwards during a 2011 game against the New Orleans Saints. That's some next-level psychological warfare right there, folks.
