2025 Fantasy Outlook
Vaki spent his rookie campaign in 2024 as a depth option at running back behind Jahmyr Gibbs, David Montgomery and Craig Reynolds, turning six carries into 14 yards and reeling in three passes for 37 yards while playing just 25 offensive snaps during the regular season. With Gibbs, Montgomery and Reynolds back in 2025, Vaki likely will operate in a similar role again, greatly limiting his fantasy upside. If he can wrestle the third-string job from Reynolds in training camp he would at least set himself up for fantasy production should Gibbs or Montgomery get hurt. Read Past Outlooks

July 29, 2025
Vaki (leg) returned to practice Monday and participated in individual drills and walkthroughs, Benjamin Raven of MLive.com reports.
ANALYSIS
Vaki missed roughly one week of training camp activities due to a leg injury, but he's now returned to on-field work in a limited capacity. The 2024 fourth-round pick suited up for 16 regular-season games as a rookie but totaled just 51 yards on offense, though he also has the versatility to contribute at safety and on special teams, which boosts his odds of being able to secure a depth role.

2024 Fantasy Outlook
Vaki is a rare athlete that has experience playing on both sides of the ball, operating as a running back and safety for Utah prior to being selected by Detroit in the fourth round of the 2024 NFL Draft. With David Montgomery and Jahmyr Gibbs already set to handle the bulk of the workload in the Lions backfield this season, Vaki will have to compete with Craig Reynolds for a depth role, making his path towards production on offense rather murky. The 5-11, 210-pound athlete seems more likely to see the bulk of his playing time on special teams in the early going.

Latest Fantasy Rumors
Lions' RB3 sans Montgomery
RBDetroit Lions
December 21, 2024
Vaki has been mostly limited to special teams work in his rookie season, but he has an opportunity to establish a larger role for himself in the backfield due to David Montgomery being sidelined with an MCL injury, Jared Ramsey of the Detroit Free Press reports.
ANALYSIS
Vaki has registered only six carries for 14 yards across 13 regular-season games. However, heading into Sunday's game against the Bears, Vaki is expected to serve in the Lions' No. 3 running back spot behind Jahmyr Gibbs and Craig Reynolds. The Lions traded up to select Vaki in the fourth round of the 2024 NFL Draft for his potential as a playmaker on offense, and that gives offensive coordinator Ben Johnson another potential weapon for the NFL's top-scoring offense.
