Finding the perfect addition to your Fantasy team via the waiver wire can be the difference between winning your league or going home with nothing. And before you determine which players you should target on the Fantasy football waiver wire this week, you absolutely need to see what SportsLine's Jody Smith has to say.

Having worked in the Fantasy industry for many years, Smith has contributed to virtually every meaningful Fantasy publication and website. FantasyPros named him the Most Accurate Expert for the 2012 NFL season. If there's anyone who knows what it takes to win a league, it's him.

Now, he's done an in-depth analysis of the best widely available free agents entering Week 8. One player Smith is advising owners to target on the Week 8 waiver wire: Cardinals running back Chase Edmonds. 

"Savvy, proactive Fantasy players already added Edmonds, who is already owned in two-thirds of CBS Fantasy leagues," Smith said. "Unfortunately, Edmonds wasn't widely started in Week 8 because incumbent David Johnson took Arizona's first snap and then was usurped by Edmonds, who proceeded to have a career game. Clearly, Johnson isn't right as the Cardinals have brought in veterans Jay Ajayi and Spencer Ware for workouts. There's a good chance Johnson could be limited or even sidelined altogether, which would make Edmonds a potential RB1 in his place. Edmonds is worth a substantial free agent bid in the few leagues where he is still available."

Smith is also all-in on a shocking running back with MASSIVE upside. This player is still widely available and could be a huge boost to your roster moving forward! Anyone who adds this player could hit it BIG. You ABSOLUTELY need to see who it is before making any Week 8 waiver wire claims.
