One of the NFL’s best running backs is holding out for a new contract. According to ESPN’s Adam Schefter, Dalvin Cook doesn’t plan on participating in any activities with the Minnesota Vikings until he gets what he believes to be a “reasonable” deal.

Cook is entering the final season of his rookie contract, set to make $1.3 million in 2020. Schefter has reported that Cook is seeking a deal worth at least $13 million a year.

Cook’s contract is worth a total of $6.353 million. According to Spotrac, 40 running backs are signed to deals that have a higher average annual value.

Houston Texans running back David Johnson, who was traded from the Arizona Cardinals earlier this season, is the NFL’s fourth-highest paid running back at $13 million a season. Le’Veon Bell is third with a $13.125 million average yearly salary. Ezekiel Elliot is second among running backs, earning $15 million per season.

The Dallas Cowboys gave Elliott a record six-year, $90 million contract in September. The Carolina Panthers made Christian McCaffrey the league’s highest-paid running back in April. After leading the league with 2,392 yards from scrimmage and 19 touchdowns, McCaffrey inked a four-year deal that pays him $16 million a season.

Cook is coming off his best NFL season. The 24-year-old was seventh in the league with 81.1 rushing yards per game. He ranked fourth with 13 touchdowns on the ground and was selected to the Pro Bowl.

Cook missed two games because of injuries, a theme of his three-year NFL career. The former second-round pick was limited to 11 games and 615 yards in 2018. Cook only ran for 354 yards in four games as a rookie.

The Vikings defeated the New Orleans Saints on Wild-Card Weekend before being eliminated by the San Francisco 49ers in the divisional playoffs. Cook had 94 rushing yards and two scores in Minnesota’s postseason victory. He ran for 18 yards on nine attempts in San Francisco.

Melvin Gordon held out for a new contract in 2019. He never received a new deal and played 12 games with the Los Angeles Chargers. Gordon is now the league’s seventh-highest-paid running back after signing a two-year, $16 million contract with the Denver Broncos.

Derrick Henry, who led the NFL with 1,540 rushing yards last year, is set to make $10.278 million next season.
