Don’t be surprised if the Buffalo Bills sign Pittsburgh Steelers kicker Kris Brown, who is a restricted free agent, to an offer sheet. The three-year veteran is coming off a miserable year, of course, one in which he missed a league-high 14 field goal attempts. But Bills general manager Tom Donahoe drafted Brown during his tenure in Pittsburgh, feels the kicker might benefit from a change of scenery, and wouldn’t mind tweaking Steelers officials a bit.
