2026 Fantasy Outlook
Vaki, a 2024 fourth-round pick, has spent his first two seasons in Detroit as a mainstay on special teams but scarcely contributed on offense, with just 10 total touches under his belt. Despite the Lions having traded David Montgomery to Houston this offseason, Vaki faces a similar fate in 2026 after the team added Isiah Pacheco to a backfield led by Jahmyr Gibbs. Additionally, Vaki’s lackluster speed (4.62 40) is an indication that his versatility may not translate from special teams to a change-of-pace role. Read Past Outlooks
RANKS
Signed a four-year, $4.67 million contract with the Lions in May of 2024.
Committee approach at RB2
Coach Dan Campbell said Monday that neither Vaki nor Jacob Saylors is viewed as the Lions' strict RB2, and Detroit will use a committee approach behind Jahmyr Gibbs, Nolan Bianchi of The Detroit News reports.
ANALYSIS
Isiah Pacheco was signed over the offseason to serve as the Lions' RB2 behind Gibbs, but he injured his back and is opening the regular season on injured reserve. Pacheco remains without a firm timetable for return, so it's Vaki and Saylors who will see elevated roles on game days. The inexperienced duo has combined for nine career regular-season carries. Gibbs is expected to have a heavy 2026 workload due to David Montgomery being out of town and now with the Texans.

Past Fantasy Outlooks
2025
2024
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.

Latest Fantasy Rumors
Momentum heading into TC
Isaiah Pacheco is currently listed as the Lions' RB2 behind Jahmyr Gibbs, but Colton Pouncy of The Athletic notes that Vaki has a real opportunity to supplant Pacheco as the team's backup running back in training camp.
ANALYSIS
The Lions traded David Montgomery to the Texans in March, opening a void at the RB2 spot behind Gibbs. Pacheco -- who played for the Chiefs for the last four years -- enters training camp as the favorite for the backup job. However, Vaki is more familiar with the Lions' offense and had an excellent training camp last year, so the 2024 fourth-rounder could earn some more offensive snaps for himself with a strong training camp and preseason. Vaki has mostly contributed on special teams through the first two years of his NFL career.
