I'd take him if he's there, but I would first try really hard to find someone that wants him that would trade up to draft him.
He's a great player and we do need playmakers, but RBs are just too easy to take out of the game by loading the box or if your OL is bad or injured. It's much harder to do that to a great WR or TE. We saw what happened when even a great RB like AK tried to run behind a terrible line with a bad scheme.
That being said, if you can't get good value in a trade down, you take him and build your offense around his talents.
