Aaron Hernandez -- Jersey Exchange Program ... MOBBED

Hundreds of New England Patriots fans lined up outside the Patriots Pro Shop today to exchange their Aaron Hernandez jerseys, and one thing was clear ... they wanted NO part of the accused murderer.

According to ESPN's Adam Shefter, more than 500 Hernandez jerseys were returned by 11:00 AM ET, which was just 90 minutes after the program opened.

TMZ spoke with a few people who waited in line to turn in their jerseys ... a few of whom had bought the jerseys for their kids and wanted to exchange the AH ones for players who were "a better role model."
