Melifonwu played in just five games with the Raiders and missed a lot of time with injury but there is no question he is a talented football player and should find a new home quickly.
"We didn't want to believe it was coming, and Coach said we weren't going to trade him", the veteran said.
"I think many of us realize we won't be here next year", the player told The Athletic.
"When what you say and what you do are two different things, there is a problem", one player told the reporter.
Carr, 27, has led the Raiders to a 1-5 start to the season, and the team's prospects are much bleaker than they were in 2016 when they went 12-4, earning consideration as budding Super Bowl contenders.
Unlike for his players, job security is not an issue for Gruden as he signed a 10-year contract before this season and is a favorite of Oakland owner Mark Davis.
"You have to wonder if we haven't been playing for draft picks all along", one player told The Athletic. Now", Smith said. "Nobody was happy when we traded Khalil. Smith said. "You never ever want to trade elite, homegrown talent".
With the Raiders seemingly open to trading anyone and everyone, Jon Gruden was asked on Wednesday about the possibility of Carr getting dealt before the trade deadline.
Raiders general manager Reggie McKenzie said Monday that the Cooper trade was about helping the team through a "great opportunity" and that there are no plans to tank the rest of the season. Cooper was pulled out of practice but Gruden didn't tell the players anything about the deal after practice was done.
"I don't see us making any more trades", Gruden said, via the Las Vegas Review-Journal.
