The Houston Texans were one of the top rushing defenses in the league this season, ranking third in the NFL in that category and not allowing a 100-yard rusher all year long.

Indianapolis Colts running back Marlon Mack didn't care about that on Saturday.

The second-year halfback punctured the Texans' defense for over 100 yards, marking his fifth 100-yard outing of the year including the regular season.

Mack is not a household name, but he may become one very soon.

The 22-year-old had a very impressive 2018 campaign, rushing for 908 yards and nine touchdowns over 12 games while averaging 4.7 yards per carry.

Mack, who played his collegiate football at the University of South Florida, was originally selected by the Colts in the fourth round (143rd pick overall) of the 2017 NFL Draft.

He had a quiet rookie year, registering 358 yards and three scores, but he has definitely broken out this season.

There has been speculation that Indianapolis could pursue Pittsburgh Steelers running back Le'Veon Bell in free agency this offseason, but with Mack's production, it might be wiser for the Colts to spend that money elsewhere rather than lock up Bell to the massive contract he is seeking.

Indianapolis won 10 games this year, rebounding to become just the third team since the AFL/NFL merger to make the playoffs after a 1-5 start.

The Colts ended up winning nine of their final 10 contests, with their only slip-up coming in the form of a strange 6-0 loss to the lowly Jacksonville Jaguars.

Indianapolis is in the playoffs for the first time since the 2014-15 campaign.
