If you think the New England Patriots undervalued Wes Welker, you should see the price the team just placed on his jersey.

The Patriots — unwilling to beat a modest contract offer from the Denver Broncos — let their leading pass-catcher join a rival on Wednesday. The next day, the club’s official pro shop at Gillette Stadium slashed prices on Welker gear by as much as 70 percent. Replica jerseys that cost $85 were marked down to $25 on Thursday.
