2025 Fantasy Outlook
Gaines and company will have big shoes to fill, replacing 2024 RB1 in college fantasy, Ashton Jeanty, in the Broncos' backfield. Gaines, a former three-star recruit out of California, got off to a fast start as a true freshman in 2024, rushing for 110 yards and a touchdown on 12 carries in the season-opener against Georgia Southern before ultimately missing the final 11 games of the season with a lower-body injury. If healthy, Gaines could be poised for a breakout campaign. However, Jambres Dubar and Fresno State transfer Malik Sherrod both figure to see opportunities as well, particularly with Gaines still limited in the preseason. Boise State also figures to throw the ball a bit more in 2025, with Maddux Madsen returning for his third season as the starting quarterback. However, the bread and butter of the Broncos' offense is still the ground game, and there is loads of talent in this backfield. Gaines has seen a lot of buzz as the top replacement, but his status should be monitored during fall camp. That said, the upside of claiming the Boise State RB1 may be too high to pass up early in fantasy drafts, and Gaines has been the name drawing the most buzz as the potential heir, though Donelson and Dubar shouldn't be wholly discounted.

September 20, 2025
Gaines was limited coming into the Week 4 matchup against Air Force, head coach Spencer Danielson told B.J. Rains of Bronco Nation News. He still finished with three carries for 34 yards.
ANALYSIS
Gaines was coming off a 14-98-1 line in the Week 2 matchup against East Washington. He was limited to three carries in this contest, and Danielson's words explained why he didn't have a big workload. It's unclear what kind of workload he'll have in Week 5 against Appalachian State on Saturday, Sep. 27.
