Anderson had spent seven years in Carolina as Cam Newton's backup, throwing all of 168 passes in that time. He was not re-signed after last season and remained unemployed until the Bills acquired him last week. With Allen injured and Nathan Peterman healthy, Anderson is the best option on the roster.
