Who Should I Start? Isaac Guerendo or Kaleb Johnson

Friday, June 6, 12:54 PM

San Francisco 49ers running back Isaac Guerendo (ankle, knee) has been taking part in voluntary organized team activities this spring after injuring his MCL and spraining his ankle in the Week 18 regular-season finale last year. Guerendo, a fourth-round pick (129th overall) in 2024, should be a full-go for the start of mandatory minicamp on June 10. All-Pro Christian McCaffrey (knee) is also back and ready to roll after missing the majority of the 2024 campaign, so Guerendo will enter the 2025 season as the backup, but Jordan Mason was traded to the Minnesota Vikings and Elijah Mitchell left in free agency. The 24-year-old Guerendo had 5.0 yards per carry on his 84 rushing attempts last year for 420 yards and four touchdowns in 16 games (three starts), adding 15 catches for 152 yards through the air. Consider him a high-upside handcuff behind the injury-prone CMC.

Pittsburgh Steelers rookie third-round running back Kaleb Johnson knows he must improve his pass-blocking skills if he wants to earn the coaching staff's trust with the hope of becoming an "every-down back" sooner than later. At 6-foot-1, 225 pounds, Johnson led the Big Ten in rushing yards (1,537), rushing touchdowns (21) and all-purpose yards (1,725) at Iowa in 2024. He's a scheme fit for Pittsburgh's zone-centric offense given his efficient production, writes The Athletic's Mike DeFabo. Even if the 21-year-old doesn't catch a ton of passes, he could stand out in fantasy with his big-play ability. There's opportunity in the Steel City, too, with Najee Harris no longer in town. Johnson is likely going to share touches with Jaylen Warren and Kenneth Gainwell, but he probably has the highest fantasy upside of the trio already.
