i highly doubt they will even try to use anderson as a full time back. if its anyone they currently have it would be musa smith as the starter and anderson to spell him. if they cant manage to get jlew back....id be highly surprised if they dont trade for/go after another RB. musa is too fragile and anderson is too old.
if they were going to let go of jamal, they really should have released him last season and held onto chester taylor
