If we sign Johnson I'd be happy with the move. He's still good enough to be effective in this league and without that injury he'd have rushed for over a thousand yards last season. Put him in a combination with Ajayi and we'd have a good duo to go forwards with. He can also catch and do the relieving side of things which is important in Gase's system, something which Alfred Morris isn't known for, so I can't see us being interested in him. Though Starks could be a possibility, however he is a true definition of a number two or role playing running back, he's not really someone we could rely heavily on if needed, so it would mean Ajayi or another back would be the featured back. For me, I think we'd be better off signing Johnson and pairing him with Ajayi, or my preferred in Foster and Ajayi.
