He's still one or two of the best backs on our roster. (Which isn't saying much)
Brown hasn't shown much, Rivers is merely depth and for some reason many are putting hope in a 5th round pick coming off of the IR.
If Henderson gets injured, which odds suggest he will, it might be better to have Akers on the roster than off.
Who knows, maybe a few more games riding the pine and he'll come to the conclusion that his career is better off showing he can still play.
