The Jacksonville Jaguars came to play on Sunday. The defense terrorized Pittsburgh Steelers quarterback Ben Roethlisberger all afternoon. Blake Bortles was steady, if not magnificent. But the real star of the day was Leonard Fournette. The rookie running back has been displaying his potential all season. He took his game to the next level on Sunday, running rampant on the Steelers' vaunted defense and showing some athleticism that could foreshadow the rise of one of the best players in franchise history.

Fournette takes Steelers to task

When the Jaguars took the field on Sunday, the star running back stood out before the game even commenced.

He was rocking cleats that made him look like the living embodiment of the team's logo. Then, Fournette became an animal on the field, running with a ferocity that will one day be the envy of the NFL.

First, he soared. Fournette flew over every player in the way on his way to the first touchdown of his day, showing people his incredible athleticism.

Then, he taunted. During a run in the fourth quarter, the Jaguars back found some open space along the side of the field. As he ran in the open field, he appeared to goad the Steelers defenders to tackle him, waving them towards himself. Eventually, Mike Mitchell laid out Fournette and tried to pump up his defenders in the immediate aftermath.

Fournette wasn't done yet, though. With time running out in the game and the Jaguars sporting a two-touchdown lead, the running back took a carry from the team's own 10-yard line, an attempt to run out the clock. Instead, he blew past the defenders and down the field for a 90-yard touchdown run, just the third touchdown run of that length the Steelers have ever surrendered.

Fournette finished the afternoon with 181 yards and two touchdowns as Jacksonville topped Pittsburgh, 30-9.

Fournette is for real

After rushing for 100 yards during his Week 1 NFL debut, Fournette had yet to eclipse that mark (on the ground, anyways) since. He turned that around with his best ground performance of the season on Sunday. The fourth overall pick in the NFL Draft is now second in the league in rushing yards with 466, only trailing fellow rookie Kareem Hunt.

Jacksonville wanted a star running back to ease the burden on Bortles, who has struggled to earn his role as the team's starting quarterback. Fournette has taken it a step further, taking on the burden and owning it like no player in Jaguars history.
