Who Should I Start? Isaac Guerendo or Jaydon Blue

An MRI exam on Monday morning revealed that San Francisco 49ers rookie running back Isaac Guerendo (ankle, knee) suffered an MCL sprain and an ankle sprain in the loss to the division-rival Arizona Cardinals on Sunday in the Week 18 regular-season finale, according to a source. Guerendo will have plenty of time to heal up in the offseason, and the best news is that he didn't suffer any damage to his ACL. Both of the injuries are to his left leg. The 24-year-old fourth-round pick didn't see much of an opportunity in 2024 until late in the season when both Christian McCaffrey (knee) and Jordan Mason (ankle) were ruled out for the year, but when he did get his chances, he was pretty effective out of the Niners' backfield. Guerendo finished with 5.0 yards per carry for 420 yards and four TDs on 84 carries through 16 games. He should serve as valuable insurance for McCaffrey in 2025.

The Athletic's Jon Machota writes that he thinks Dallas Cowboys running backs Javonte Williams, Jaydon Blue, Miles Sanders and Phil Mafah will end up getting almost all of the backfield work for the team in 2025. Machota sees Williams being the leader early in the season, but eventually the rookie Blue will get more carries and lead the team in rushing. Machota thinks that by the end of the year, Blue, a fifth-round pick this year, will be their No. 1 RB. The 21-year-old Texas product is staying in state and will bring much-needed speed to Dallas' backfield this year. The 5-foot-9, 196-pounder isn't all that big, but he should complement the power of both Williams and Sanders well and provide a nice change-of-pace option with some pass-catching upside. Volume will certainly be a concern early on in Blue's rookie season, but he's not a bad late-round sleeper target for fantasy managers that wait at the position.
