'"(Gilmore)'s playing at a high level," Thurman said. "You don't to compare athletes one versus the other. You want to give each athlete his due. Gilmore played at a high level a year ago and we anticipate he'll continue to play at a high level. Can a player improve? Sure they can. Our expectation is that all the guys on the defense with the Bills, matter of fact every guy on this team, will look to improve and become a better football player for 2015."'
