NAPA, Calif. -- The Oakland Raiders once again spent big to lock up one of their own key players, signing a five-year, $48 million contract with linebacker Kamerion Wimbley on Monday that gives the team more room under the salary cap and Wimbley $29 million in guarantees.
"It was in my best interest and the team's best interest to try to work out something long term to try to get some players in here this year to help make us a better team," Wimbley said. "I was with that. I'd just like to thank Al Davis and the Raiders organization to allow me the opportunity to be here for more years and to give me the chance to prove myself and play for the Raiders."
Now the question remains whether the Raiders will be able to use the salary cap savings to get two more of their free agents into camp: unrestricted tight end Zach Miller and restricted running back Michael Bush.
A league source told ESPN.com's Bill Williamson that Miller, who has led the Raiders in receiving the past three years, was in Seattle visiting the Seahawks on Monday, raising questions about whether he will stay in Oakland.
"Zach was a Raider last year, we want him to be a Raider now," coach Hue Jackson said. "That thing is going to come to a head here soon. It has to. I feel good about where we are and, hopefully, he'll get back to us, we'll get back to him, and we'll try to get something resolved."
Wimbley had been set to play for the $11.3 million franchise tag tender before agreeing to the long-term deal that makes him one of the highest-paid linebackers in the game. Now he knows he will have to deal with the pressure that comes with his lofty salary.
"The new contract has to be earned so I definitely look forward to the opportunity to go out and playing and earning every bit of the contract," he said.
It's been quite a year so far for Wimbley and his contract. The Raiders originally hoped to use a $3.5 million buyback option to keep Wimbley under contract for next season for just over $4.1 million.
But the NFL determined in February that the deal violated rules prohibiting base salaries rising more than 30 percent in a year. That led to the Raiders decision to use the franchise tag.
Then with Oakland looking to lower this year's salary cap hit from the $11.3 million franchise tag, Wimbley got an even bigger deal that spreads out the salary cap hit.
"The Raiders showed how important Kamerion is to the franchise," said his agent, Joe Linta. "He is elated and happy to make his future with the Raiders and help get them a championship."
Wimbley entered the NFL with high expectations after being drafted 13th overall by the Cleveland Browns in 2006. He had 11 sacks as a rookie in a promising start to his career.
He was unable to match that production in his final three seasons in Cleveland, recording 15.5 sacks in that stretch and was traded to Oakland by new president Mike Holmgren for a third-round pick.
Wimbley quickly thrived in Oakland, playing outside linebacker in the base 4-3 defense and then moving to defensive end in passing situations to take advantage of his pass-rushing skills.
"He is so versatile," linebacker Quentin Groves said. "He is big and athletic, can stop the run on first and second down and then rush the passer on third down. He is a great guy in the locker room as well. If somebody has a question, they go to Kam. He is a silent leader. He leads by actions and by example. He doesn't say a whole lot, but every now and then he tries to joke around a little bit. Couldn't have happened to a nicer guy."
He led Oakland with nine sacks last season and is being counted on for even more this year.
"He's a tremendous player, a tremendous young player," Jackson said. "I know he has nothing but an unbelievable upside ahead of him. Nine sacks a year ago, I expect more than that, more of that, and he'll do that for this organization."
