The NFL makes a ton of money off of jersey sales to fans. Me--I'll never buy one. It is not that I don't love my team enough to show that level of support, but for as much as they cost I don't want to spend the cash only to see the man retire early, get traded, or change teams two years later when he becomes a free agent.
But this guy; this guy might have found the jersey of the one player that will never be traded. Folks will always want him. They will always enjoy him, and when he leaves folks will want him back.
