Week 4 Waiver Wire: Roy Helu and 2 RBs to Sign Now

To successfully work the running back waiver wire, you have to stay one step ahead of your competition. The RB field is usually pretty well picked over, which means to rule this position, you have to be forward thinking. Here are three that will help you accomplish that.

*Note: League availability numbers are via NFL.com.

Washington Redskins' RB Roy Helu

For two weeks in a row, Roy Helu has been getting the majority of the second half carries for the Redskins. I don't expect it to be too much longer before he supplants Tim Hightower in the starting lineup.

The Redskins rush offense struggled vs. the Cowboys, but the Cowboys have a very good rush defense. Most weeks, this offense will put up decent numbers, and Helu will soon be leading the way.

He is also a solid threat catching the ball out of the backfield. Helu is available in 47 percent of leagues.

Oakland Raiders' RB Michael Bush

All reports indicate that Darren McFadden is going to be fine for this Sunday's game, which confines Bush to back up status, but he is still getting points. Bush will get touches every game as he spells McFadden, and he is also the Raiders short yardage and goal line back.

This means Bush is going to get his touchdowns. Bush is only available in 26 percent of leagues, and if he is available in yours, he is a viable flex option right now. And should Darren McFadden miss any time, Bush will be a front line starter. 

New England Patriots' RB Stevan Ridley

Patriots running backs are always a risky play. They seem to have a constant revolving door at the position, and no one player ever shines. That said, Ridley has the potential to be a decent producer, as he may be working himself into a starting role there.

Ridley was far and away the Patriots best RB in Sunday's loss to the Bills. He rushed for a team-high 44 yards on seven carries and caught one pass for eight yards.

He is in line to get more touches this week, and if he does become the feature back, this move could pay huge dividends. He is also available in a whopping 99 percent of leagues.
