Coming off two straight strong games, the last one where Marques Colston had seven catches for 118 yards and a touchdown, it may be a good time to sell high on him.
This just happens to do with my theory of when a team, like the New Orleans Saints and Green Bay Packers, have a loaded wide receiver corps combined with QBs who share the ball around; it just does not translate into consistent fantasy results.
Colston is the Saints' No. 1 WR on the depth chart, but is he really in games? Drew Brees has a WR corps of Devery Henderson, Lance Moore, Robert Meachem and what seems to be his favorite target these days—tight end Jimmy Graham.
Brees will look for Colston, but if he is not open, he is smart enough to not force it and just throw to the open receiver.
This system leads to inconsistent fantasy play, and you will be better off with a receiver on a team that relies on just one or to receivers.
If you can make a trade like that, do it.
