Jay Ajayi could gain a more featured role in the offense. He showed flashes of play making ability when given the ball last season, so give him the ball. He is also very capable of catching the ball and making plays. Would I want him to be our every down back, given 20+ touches a game? I'm not sure because of the injury concerns. But he is definitely capable of 10-15 touches a game in a more prominent role.
Damien Williams has shown flashes of play making ability in a very limited role. He has good hands and can catch the ball, he can carry the ball. Again utilise the talent on the roster. He might not be a starter on this roster, or even more than the third guy on the depth chart, but he is capable if given a chance. Give him a handful of touches a game.
At this point if we run an offense similar to Chicago, one that run the ball 29 times on average last season, what we would need to find in free agency or the draft is a back that is capable of being an every down back and contributing alongside Jay and Damien. Chris Johnson showed he can still make plays in the NFL last season with Arizona, he would come fairly cheap. Ronnie Hillman showed play making ability with the Broncos, again he shouldn't be overly expensive. And what about Arian Foster, we wouldn't need him to carry the load like he did with Houston, he again could be fairly inexpensive on a one or two year deal. If we paired a veteran with Jay and Damien, I think we'd have a good trio of backs to go forwards with. Or we could try and find another back in the draft, though whether we would want a trio of young inexperienced running backs is debatable.
For me, this isn't bad news as such that we aren't getting CJ Anderson. He is talented and I would have liked him on the roster, but there are other capable backs available in free agency and the draft that could contribute to our running game. And that's without considering Jay could be promoted to a more prominent role in this offense.
