Who Should I Start? James Conner or Alexander Mattison

Arizona Cardinals running back James Conner (knee) took part in voluntary organized team activities on Wednesday. "I'm ready," Conner said. "We ain't doing this forever." Conner injured his right knee in Week 16 of last year and had six touches before being pulled in Week 17. The Cardinals placed him on Injured Reserve for the Week 18 regular-season finale, but the 30-year-old veteran appears to be fine now and ready to go for the start of the 2025 season this fall. He racked up a career-high 1,518 scrimmage yards on 236 carries while catching 47 of 55 targets in 2024. It was the healthiest Conner had been in his career, so fantasy managers definitely should expect some more missed time given his age and physical running style. For now, he's still being considered a workhorse back in Arizona, but more injuries could give Trey Benson more of a role eventually.

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.
