NFL insider Dianni Russini has opened up on the contract standoff between the Buffalo Bills and star running back James Cook.Cook is entering the final year of his rookie deal, and he has been holding out of practice and preseason games as he looks to get a new deal. However, Russini believes that Cook's asking price is deemed high."Yeah, it's certainly not great. We saw Kyren Williams out of LA get paid around $11 million (per year). We know that James has said publicly that he thinks his worth is about $15 million," Russini said. "Credit to him, he's shooting high. He knows he's valuable to this offense, and we saw the effect that Saquon Barkley had on the Philadelphia Eagles and their run."As Russini notes, the Kyren Williams extension is the number many people expect Cook to sign for.But the insider says this is an odd spot for Brandon Beane and the Buffalo Bills, as they haven't had a holdout before."No one thinks that number is realistic. I think the number makes sense right around Williams, even not a million or two more," Russini added. "The only reason this one is slightly bizarre to me is if you just look at the Buffalo Bills' history and Brandon Beane even said it, he's been there nine years, they've never dealt with anything like this. It's quite the track record."Cook finished last year, rushing for 1,009 yards and 16 touchdowns on 207 carries. He added 32 receptions for 258 yards and 2 touchdowns. The year prior, he had 1,122 yards and 2 touchdowns on 237 yards.Bills coach expects James Cook to practiceJames Cook sat out some practices and a preseason game as he looks to get a new deal.However, heading into practice on August 12, Bills coach Sean McDermott expects Cook to return to practice.Matt Parrino @MattParrinoLINKJames Cook is expected to practice today, per Sean McDermott.
