Eight weeks into the season, you're either feeling good about your playoff chances or you're on your last legs. One more loss could mean calling it a season in your league, forcing you to play the sorry role of spoiler the rest of the way. But one more win could open up the possibility of a Fantasy league title run.

Knowing what you need to do to starts with taking inventory of your roster. If you have good depth, especially at running back -- and especially this week -- you need to make a move. And if you don't have depth and need some starters, the time has come to consider dealing one great player for two very good starters. If you're sitting on two losses or fewer, you might want to find a way to land a big-time stud on your team, if only to keep lineup decisions from getting complicated moving forward.

In every league, bank on seeing some two-for-one deals. This is the time of year for them because this is the time of year people get serious about Fantasy Football. The two-for-one deal typically is a win-win -- one team picks up a big-time player by liquidating some depth and the other team gets two good players they can set in lineups immediately.

The Trade Values are perfect for lining up two-for-one swaps. Let's check some deals being offered that could spur some action in your leagues:

Martavis Bryant and Doug Martin for Rob Gronkowski: This is a classic example of the two-for-one. A team interested in landing a stud tight end takes advantage of the depth he or she cultivated throughout the year. By trading for Gronk, the owner eliminates any lineup headaches Bryant and Martin might have caused. Subsequently, the team giving up Gronk lands two starters to help with a playoff push.

Ben Roethlisberger and Shane Vereen for T.J. Yeldon: Here we have an awful two-for-one where someone basically gives away Roethlisberger to upgrade from Vereen to Yeldon. Is Yeldon the better running back? Yeah, but not that much better.

DeMarco Murray and Matt Forte for Adrian Peterson: Many are quick to nix this deal because Peterson's considered a hot commodity, but he hasn't been himself in the stat sheets. He hasn't posted a monster game since Week 3 and last had more than 10 Fantasy points in a standard league in Week 4. Getting a potential stud in Murray and a back worth being patient with in Forte for Peterson might not end up being so bad. It's worth thinking about for owners with Peterson and another stud running back like Devonta Freeman or Todd Gurley.

Michael Floyd and Michael Crabtree for Randall Cobb: Is this a bag of fool's gold for a potential superstar receiver who hasn't played well lately? Or is it a rip-off? Cobb hasn't been close to expectations for a while now, and Floyd and Crabtree are playing some really great football.

Danny Woodhead and Jordan Reed for Alshon Jeffery: This one's pretty perfect. Jeffery is a no-brainer starter but so is Reed and Woodhead should be in starting consideration fairly often. In essence, a team looking for capable starters cashed in Jeffery for two real nice ones.

What are the Trade Values? The chart is designed to help guide you in making fair trades in your standard-scoring or PPR leagues. The values assigned to the players below are a long-term measurement of their Fantasy value. By adding two players' values you could determine what one player you should be able to get in return. This list should also work as a "Rest of Season" rankings. Also, any player not on the chart should be considered valued at no more than three points.
