The Charlotte-to-Cleveland pipeline is officially open, although the first ex-Carolina player to join Rob Chudzinski with the Browns is not the one most expected. Free agent tight end Gary Barnidge has agreed to terms on a three-year deal with Cleveland, his agent said Wednesday. Barnidge, the No. 2 tight end behind Greg Olsen in Charlotte, hopes to have more pass-catching opportunities in Cleveland, where Chudzinski took over for the fired Pat Shurmur following two seasons as the Panthers’ offensive coordinator. After Chudzinski was hired in January, Panthers backup quarterback Derek Anderson created a stir by hinting on his Facebook page that he might return to Cleveland to tend to “unfinished business.” Anderson spent his first four seasons in Cleveland, and went to the Pro Bowl in 2007 when Chudzinski was the Browns’ offensive coordinator. But a Chudzinski and Anderson reunion in Cleveland is not likely to happen, league sources said Wednesday.
