‘It became clear the Bills were looking for upgrades at the position when General Manager Brandon Beane drafted over Williams and Foster twice. Davis and Hodgins, both of whom were impressive during training camp, are two of six receivers kept on the initial 53-man roster, joining Stefon Diggs, John Brown, Cole Beasley and Isaiah McKenzie. In somewhat of a surprise, the Bills released veteran receiver Andre Roberts, whose main job last year was returning kickoffs and punts. That move is expected to be short-lived, though, as a league source told The News that Roberts could rejoin the active roster as soon as Sunday, provided Roberts doesn’t have a sudden change of heart and sign elsewhere.’
