Players who are cut or waived by teams on the final roster cutdown aren’t always purely a matter of them not being worthy of the final 53. Sometimes it’s a matter of making too much. At least too much in relation to how the team values them. Or they just value another player just as much but that other player is cheaper.
What this means is not only will the Raiders be making moves that are based at least partially on that player’s salary, but other teams will too. And if the Raiders are to partake in either claiming one of those players off waivers or signing them after they’re cut, they will have to have the cap space to do it.
