I think Benson would be desirable to a team dealing with injury/depth issues at RB. He is still young and if he can show that he is healthy then I believe that teams would find him as a desirable RB who could add additional depth. With the limited carries that he had last season splitting time with Conner he showed that he could break some big runs and catch the ball out of the backfield.
However with his latest MCL injury to the already reconstructed knee, that would probably limit him to a smaller load moving forward. I don't believe he will every be a Workhorse 20-25 carries a game RB anymore as that would eventually cause flare ups in his knee like he is dealing with right now. However if he can get healthy enough to show that he can handle 10-12 touches per game load I think he could grab some teams attention. Hopefully he can get the inflammation under control enough to show something in the next 4 weeks.
