What do I mean by a darkhorse player? It is a player that people don't expect to have a big impact but surprises everyone by outperforming expectaions having a big immediate impact. First round and 2nd round picks, to a lesser extent, aren't darkhorse candidates. They are expected to make an immediate impact. My pick is Turbin. He isn't on the list of top 5 runningbacks but I think he can play. Who is your's?
