Davis was tied for the lead in targets this week.
I would agree that normally, the type of x-factor offensive playmakers we're talking about are found in the first round. Harvin, Best, Bush, Spiller. Cobb may be an exception, as well as Sproles but that was in a time when a player of his skills was less valued. McCluster was an attempt at a similar player, but he's not really what I'm looking for.
I think Denard Robinson may be an exception in that if you're comfortable with your projection of him as an explosive talent from the RB/WR/KR/PR positions, you may be able to get him later than your normal player of that skill-set....precisely BECAUSE he isn't proven in those categories. I could easily see him available in the 2nd to early 3rd. It all depends on how comfortable you are with his questions marks.
