The Raiders very nearly traded for Seahawks backup quarterback Matt Flynn on Friday, with the deal hanging in the balance as general manager Reggie McKenzie waits for Flynn to sign off on a pay cut, league sources said. With high-priced quarterback Carson Palmer unreceptive to a proposed pay cut, Oakland will give up two conditional draft picks to Seattle if Flynn signs off. Flynn, 27, is a five-year veteran who has made just two starts and attempted 141 passes. He spent his first four seasons with Green Bay, and McKenize worked in the Packers’ front office when Flynn was selected in the seventh round of the 2008 draft. He was signed by Seattle last season but lost the starting job to rookie hotshot Russell Wilson.
