According to this writer, he's pretty close. In at #2:
2. Jarrett Boykin – Packers
Per PFF, no team had three or more wide receivers on the field more than Green Bay last season (79 percent). With James Jones now in Oakland, Boykin has been promoted into a role that puts him behind only Jordy Nelson and Randall Cobb for targets. He’s a borderline WR3.
While I like Boykin, not sure if I would rank him in the top 2 just yet. But then again, MM was gushing over this kid last month. GB has big plans for him.
Side note: ESPN Sux also has a debate about who GB's #1 WR is. Nelson or Cobb? IMO, gotta give the edge to Jordy. Still has to be one of the most underated #1 WR's in the NFL. Kind of like DD in the early mid 2000's.
