Who Should I Start? Alexander Mattison or Isiah Pacheco

Miami Dolphins running back Alexander Mattison (neck) was officially placed on injured reserve on Monday. Mattison injured his neck during a preseason game against the Chicago Bears on Sunday and later went for surgery. It was announced on Monday that he would miss the remainder of the year, with the team placing him on IR just as a procedural move to clear roster space. Mattison's absence will open up reps for second-year running back Jaylen Wright and rookie Ollie Gordon II behind starter De'Von Achane.

After an injury-marred campaign in 2024, Kansas City Chiefs running back Isiah Pacheco entered 2025 in need of a bounce-back effort. Unfortunately, the 26-year-old struggled with inefficiency, recording 563 scrimmage yards and two touchdowns on 137 touches across 13 games played. Pacheco averaged just 3.9 yards per carry, his second-straight season under four yards per rush attempt after averaging 4.7 yards per carry over the first two years of his career. Pacheco spent most of the 2025 season splitting backfield work with veteran Chiefs running back Kareem Hunt, with Hunt dominating touches in short-yardage situations and around the goal line. Pacheco is now set to hit unrestricted free agency, so he's not guaranteed to be back in Kansas City. Based on his performance over the last two seasons, it's not hard to imagine a scenario where Pacheco finds himself in a committee backfield or even a straight RB2 role for the 2026 season. In dynasty formats, Pacheco's future fantasy value profiles as uncertain at best coming off his shaky 2025 campaign.
