FLOWERY BRANCH — Newcomer Mohamed Sanu wouldn’t be “remiss or a fool” to say he didn’t have a chip on his shoulder entering Atlanta Falcons Training Camp on Thursday. “I’m a man, I’ve got pride. So I got a lot to prove to myself and to a lot of people down here saying I can’t do something. ...You know I got a lot to prove,” said Sanu, who signed a hefty five-year deal worth $32.5 million despite recording just 33 catches and no touchdowns in 2015.
