You might want to trade one of your big 3 (nice receivers btw) to get a good rb. Coles will service as a very capable wr and put up good numbers, so you won't have as big a dropoff if you were to get rid of Moulds or Plexiglass for a stud rb. Common wisdom states that rb's will score more than wr's, so I suggest this as the way to go.
If you can get some n00b to trade you someone decent for Rogers this week DO IT. His stock this year will *never* be as high as it is right now.
He may very well be the 'real deal' next year, or the year after, but I guarantee he's not going to flower under the 'special attention' he's going to get in the upcoming weeks.
He might be worth a spot at the #3 WR position on someone's team, but if you can trade him for anything decent at RB or QB I say pull the trigger.
