Here's how I look at it: would I rather have ...
A.) Wolford or Perkins throwing to Kupp, Robinson, Jefferson, Skowronek, Higbee, Blanton, Hopkins, Harris, Akers, Henderson (and possibly OBJ)
-or-
B.) Stafford throwing to Robinson, Jefferson, Skowronek, Higbee, Blanton, Hopkins, Harris, Akers, Henderson (and possibly OBJ)
For me it's an easy choice: B
Not necessarily because I think Stafford is better than Kupp, or even that Stafford is a better QB than Kupp is at WR. It's because the drop off at QB without Stafford is significantly greater than the drop off in potential receivers without Kupp.
