Trading is all about getting the best value for your players, and among the better trading strategies is to target players whose perceived value is low due to recent poor play. Such players are often called "buy-low" candidates, and here are four I'd go get right now:
Joseph Addai, RB, Colts: That coach Tony Dungy says he plans to keep splitting the rushing workload between Addai and Dominic Rhodes should only serve to keep down Addai's trade value, but don't buy the talk. Addai continues to see his role in the offense increase, while Rhodes' performance only worsens each week. Maybe Rhodes' eventual role is goal-line back, but I still see Addai getting enough carries to have No. 2 RB upside.
Chris Chambers, WR, Dolphins: Maybe he hasn't done anything to warrant the top-10 receiver status he achieved on draft day, and maybe he lacks the top-notch quarterback throwing him the ball. But hasn't that been the case his entire career? What's important is that Chambers is a phenomenal second-half player. In 2005, he had all three of his 100-yard efforts and eight of his 11 TDs from Week 10 on, and in 2004, he had all four of his 100-yard efforts and five of his seven TDs in his final 10 games. Chambers regularly heats up as the weather cools in November and December (OK, only slightly in South Florida), and while Joey Harrington might be erratic, he's capable of getting Chambers the ball.
