As fantasy football owners can see, trade value for players on their rosters is always on the rise or decline. The stats above are C.J. Spiller's, and if you were a smart fantasy football owner, you would have traded him by now.
With Week 6 starting tonight, find out whether you should buy or sell the trade value on some of the hottest names in fantasy football.
I know Matthew Stafford has not lived up to the fantasy hype he got after his breakout 2011 season, but he still has put up solid numbers.
Though the Detroit Lions have only won one game, Stafford is still on pace to throw for over 4,700 yards this season. His three touchdown passes through four games have not been impressive, but once the Lions get back on track, Stafford's fantasy numbers will get significantly better.
Right now in most fantasy football leagues, you can get Stafford at a low trade value because of his underachieving performance so far. He is definitely worth the risk if you are in need of a quarterback. The Lions offense has too much talent, between Stafford and Calvin Johnson, to not put up more points.
Any time you can get a quarterback like Stafford who throws the ball more than 40 times a game, he is most likely going to put up double-digit fantasy numbers each week.
Those who were smart enough to trade Chris Johnson after his Week 4 performance, where he ran for 141 yards, definitely got great value in return.
Johnson's time as an elite fantasy football running back is over. Since last season, Johnson has scored four touchdowns and surpassed 100 rushing yards in only five games. His 2012 season is going to be just as underachieving as his 2011 season.
It will be tough to find someone to trade for Johnson, but maybe there will be one sucker in the league who thinks he still has something left in the tank. I would suggest waiting until he has another decent outing, but that may not happen again this season.
If there are any fantasy football owners in need of acquiring a running back, they have to make Alfred Morris their No. 1 target.
Morris is the most underrated running back in this fantasy football season. He is consistently putting up top-10 fantasy running back numbers, yet people still do not give him the love he deserves.
Through his first five games, Morris has averaged 20 carries a game while finding the end zone four times. In each of his last two outings, Morris has surpassed 100 yards rushing.
What makes Morris even more valuable is that he is the Washington Redskins goal-line running back. Any time they are in the red zone, know that Morris is guaranteed to get the carries. With Robert Griffin III coming off a concussion, look for Griffin to run a little bit less and for Morris to get more of a workload.
After the first two games of the season, there was not a better player in fantasy football than C.J. Spiller.
A lot of that had to do with the fact that the other running back in the Buffalo Bills backfield, Fred Jackson, was injured. Now that Jackson is gone, the Bills have gone back to a split backfield, and Spiller is no longer a reliable fantasy running back option every week.
His trade value has taken a major hit after combining for only 15 carries for 57 yards in his last two games. Someone else in the league will be desperate for a running back, so look to offer Spiller. Hopefully they will think he will return to his Week 1 and 2 form.
Year after year, every fantasy football owner thinks Dez Bryant is going to have a breakout season. He has all the tools to be one of the best wide receivers in the NFL. He has the size, the speed and plays in a pass-heavy offense.
Despite having everything set in place for Bryant to have a successful career, it is time to give up on him.
In his first four games this season, Bryant has failed to score a touchdown while only recording 269 receiving yards. Sure, he had more than 100 receiving yards his last game, but Bryant could have had way more if he did not drop three passes.
Bryant is never going to be better than a low-end No. 2 fantasy receiver as long as Miles Austin and Jason Witten are still with the Dallas Cowboys. Austin and Witten have shown they can produce on a consistent basis, and Tony Romo trusts them more.
