The Texans signed RB Marlon Mack to a 1-year deal. Mack tallied 1,999 yards and 17 TDs on 4.5 yards per carry across his 2nd and 3rd NFL seasons. But he tore his Achilles in the 2020 opener and totaled just 28 carries for 101 yards behind Jonathan Taylor and Nyheim Hines in Indianapolis last year. If somewhere close to 100%, though, Mack might just be the best in a Houston backfield currently sporting only Rex Burkhead, Royce Freeman and Dare Ogunbowale. We'll see if the Texans add more in the draft. Mack just turned 26 last month.
