October is up to its tricks again. In Week 6, we had a ghost sighting of the Adrian Peterson from his prime. The newly acquired Arizona Cardinal arose from the dead, carrying the ball 26 times for 134 yards and two touchdowns. The 32-year-old proved he stills has a lot left in the tank. Peterson stole the reigns to the starting job and seems to be a clear cut RB2 for the rest of the season. This is a great example of how quickly things can change in the NFL and for fantasy. If you missed out on Peterson, here are some other great waiver adds heading into Week 7.

Washington Redskins’ tailback Robert Kelley is expected to resume practice this week after missing the last couple weeks with rib and ankle injuries. During his absence, his ownership has dropped to just below half of all Yahoo and ESPN leagues. Kelley seems to have been forgotten about within the fantasy community and will make for a crucial upgrade at running back heading into the stretch.

Wendell Smallwood of the Philadelphia Eagles is another must add that has seen his ownership decrease since missing the past two weeks with a knee injury.

The New York Giants seem to have found their mojo in fourth-year back Orleans Darkwa. Darkwa rushed for 117 yards on 21 carries for in the Giants’ first win of the season. He is the first tailback this year to get 100 yards or more on the Broncos’ stout defense. Darkwa has taken over the lead role for the 1-5 Giants and will continue to see volume as they have lost most of their effective pass-catching weapons.

It’s hand-cuff time. As the midway point of the season approaches, teams need to back-up their studs, more specifically high-end running backs. Take precaution. Sacrificing a roster spot now on a back-up running back could pay huge dividends come playoff time barring an injury.

As for wide receivers, John Brown of the Arizona Cardinals looks to be fully healthy and has posted back to back touchdown games. Brown makes for a great bye-week fill-in with massive upside as he has shown great chemistry with quarterback Carson Palmer when healthy in years past.
