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.

The Indianapolis Colts added former Kansas State running back DJ Giddens in the fifth round of the 2025 NFL Draft, and James Boyd of The Athletic believes he is poised to beat out Tyler Goodson as the team's top pass-catching back. The team added Khalil Herbert this offseason to replace Trey Sermon, but Giddens profiles as more of a receiver after snagging 50 receptions over his final two collegiate seasons. That said, Indianapolis ranked 30th in total running back targets a season ago (65), so Giddens is unlikely to have standalone upside as a backup to Jonathan Taylor. Instead, he'll be more of an interesting handcuff back that could have flex value in the case of a Taylor injury. Giddens was a fifth-rounder, though, so it's too early to assume he'll have any role in Indy's offense.
