Who Should I Start? Alexander Mattison or DJ Giddens

Thursday, March 13, 9:35 PM

Former Las Vegas Raiders running back Alexander Mattison is signing an undisclosed deal on Thursday with the Miami Dolphins, sources told FOX Sports' Jordan Schultz. Earlier in the day, former Dolphins RB Raheem Mostert signed with the Raiders in free agency. The 26-year-old Mattison joined the Raiders in 2024 after spending his first five years in the NFL with the Minnesota Vikings. He eventually took over the lead-back role from a disappointing Zamir White and carried the ball 132 times for 420 yards and four touchdowns (a career-low 3.2 yards per tote) in 14 games (seven starts), adding a career-high 36 catches for 294 yards and another score. Mattison's move to Miami is a big downgrade, as he'll merely be competing for a change-of-pace role with Jaylen Wright behind unquestioned starter De'Von Achane. He'll be avoidable in most fantasy drafts this fall.

Indianapolis Colts running back DJ Giddens has had a strong start to training camp and looks like the RB2 behind workhorse Jonathan Taylor. Giddens has ripped off a few highlights on cutback runs as the pads have come on in practice. Head coach Shane Steichen has provided glowing reviews of the team's 2025 fifth-round pick, saying, "he's kind of a glider." He continues gushing about his burst and vision, as well as his ability to thrive on outside zone runs. The Kansas State product is seen as a potential third-down back who has the ability to be dynamic as a runner and as a receiver out of the backfield, with Steichen noting his "natural" hands. As part of a really strong 2025 running back class, Giddens has a strong collegiate profile with a career 6.0 yards per carry at Kansas State. He is one of the more valuable handcuffs in fantasy this year behind Jonathan Taylor.
