Top-selling jerseys: NFC North

Before we move full speed into training camp coverage, let's take a look at a chart that reminds us why there is so much anticipation about the NFC North's 2013 season.

As you can see, the jerseys of three players with NFC North connections were among the 10 highest selling in the NFL between April 1 and June 30, via ESPN's Darren Rovell. That includes former Chicago Bears linebacker Brian Urlacher, who ranked No. 10 even though he announced his retirement on May 22.

The others are Minnesota Vikings tailback Adrian Peterson, who checked in at No. 4, and Green Bay Packers quarterback Aaron Rodgers (No. 9). Peterson, of course, was the centerpiece of the Vikings' rollout of redesigned uniforms just before the draft.

My training camp tour will begin later this week at Location TBA, at which point I'll commence a summer-long survey of jerseys just to confirm that this list is accurate.
