Knowshon Moreno, Denver Broncos
After it appeared that Ronnie Hillman was going to be the Broncos' new starting running back, Moreno got the start this past week and made the most of it.
Though he didn't have a great game, Moreno still had 20 carries and four receptions. If he continues to get this many touches, Moreno will be a terrific flex play for the rest of the season.
Bryce Brown, Philadelphia Eagles
We don't know how long LeSean McCoy is going to be out for, but what we do know is that Brown can certainly ball. Filling in for McCoy this past week, Brown ran for over 170 yards and two touchdowns against the Carolina Panthers.
Even if McCoy returns this week, expect Brown to have a much bigger role in the Eagles offense after this impressive performance.
Beanie Wells, Arizona Cardinals
Despite missing most of the season, Wells returned this past week and immediately had a fantasy impact. Though he only ran for 48 yards, Wells was still Arizona's go-to running back, receiving 17 carries and scoring two touchdowns.
Wells may not run for many yards, but he is going to get plenty of goal-line carries that should result in a good amount of touchdowns.
