"I think any time a player reaches that age of 30 or close to that age of 30, and you know that the guy can still play, you know that he is a very talented player," O'Brien said at the NFL Scouting Combine. "Arian is a very talented guy in a lot of phases. He can run the ball, he can catch the ball, he's a good pass protector, he's a smart football player, but you've got to manage him. How do you manage that? You manage him in practice. You manage him in the games.
"That's something we'll always take into account. We communicate with the player. We communicate with Arian. How are you feeling this week? What's ailing you? Things like that. You take a lot of hits at running back in this league. I think we just continue to communicate with Arian and manage it. He's got a lot of good football yet."
"I think when you look at our needs in the draft, I would say running back is a position that we could look at."
