Usually when I see someone wearing an NFL replica jersey I think that the person either has a low IQ, is a square, or is a dumbass moron.
NFL replica jerseys are the dumbest and tackiest looking article of clothing, they look like someone got a trash bag, ironed numbers and a last name onto it and said "hey wear this to support your team!" and usually the people I see wearing them look like they couldn't pass a 5th grade level mathemetics exam.
I'd rather go naked than wear an NFL replica jersey. In fact I think a bedsheet would look better than an NFL replica jersey, pretty much the same thing.
