You make a great point about the Moss, Welker aspect and that is exactly what I mean.
We have oue "Moss" in Roddy and other role players. Coffman provides that ability to catch a ton of balls and make people cover him.
Again yes, the argument will go nowhere. But think Gresham is a first round guy compared to Coffman in the second.
So the question is, would you rather have Gresham in the 1st or Coffman in the 2nd??
