Watch the Cowboy situation, it looks like Randle may be the starter but he has off field issues. With their OL, the starting rb will get a lot of touches and Randle has potential if he can stay out of trouble.
I may break my vow to never, ever pick McFadden again but if Randle's head isn't right McFadden may not be a bad pickup in the late rounds. He will probably be overlooked due to the bust seasons he has had in the past.
I usually pick up a backup to a key player (Charles, Lynch, Murray, etc) although my Christine Michel drafts over the past 2 years have not paid any dividends
These late pickups at the rb position should keep an owner competitive.
