No, it's legit, just a factory defect. It's from a licensed apparel store and it's screen-printed. The Chinese knock-offs always have their numbers (poorly) stitched on.
It's only taking 4-6 weeks because I ordered a medium and shockingly, Spiller's great play of late has resulted in increased demand in his jersey. Does anyone know if the Bills Shop at the Ralph actually does screen printing in-house? Or press-on numbers? If that's the case, I'll just wait it out and take it there.
