San Francisco 49ers quarterback Colin Kaepernick's No. 7 jersey was the NFL's top-selling jersey from April 1 to June 30, according to ESPN's Darren Rovell.
Three other quarterbacks -- two of them who were also first-year starters last season -- joined Kaepernick in the top five based NFLShop.com sales.
Russell Wilson's No. 3 Seahawks jersey sold the second-most, followed by Robert Griffin III's No. 10 Redskins jersey, running back Adrian Peterson's No. 28 Vikings jersey and Peyton Manning's No. 18 Broncos jersey.
The 49ers are leading the offseason in jersey sales, followed by the Seahawks, Dallas Cowboys, Baltimore Ravens and New England Patriots.
San Diego Chargers linebacker Manti Te'o had the the top-selling rookie jersey, followed by the Rams' Tavon Austin, the Bill's E.J. Manuel, the Vikings' Cordarrelle Patterson and the Packers' Eddie Lacy.
Te'o, the 38th overall pick in the second round, is the only defensive player in that group.BURKE: 2013 NFL Preview: NFC West
