The Atlanta Falcons find some running back depth for training camp after signing a former San Francisco 49ers ball carrier. There's no question that the Atlanta Falcons' backfield belongs to Bijan Robinson. If he plays any games for the Falcons, this will be Sermon's fifth team in six years in the NFL. All things considered, Falcons fans will expect to see Bijan Robinson dominate the backfield. Especially after the Bijan Robinson signed a three-year, $66.75 million contract extension in August.
