Buffalo Bills linebacker Brandon Spikes has revealed that he is ready to have a big impact for the club in the 2014 season.
The 26-year-old signed a one-year deal with the club after being allowed to leave the Bills' AFC East rivals the New England Patriots.
Spikes has insisted that he has nothing to prove despite the short length of his deal with Doug Marrone's side.
He told reporters: "My whole life I've had something to prove so it just helps put some fuel on the fire.
"It keeps that burning sensation I have inside of me for the game and, like I said, whatever, if they say I have something to prove, I just have to go out there and do it."
Spikes recorded 86 tackles and one interception in the 2013 season.
