yeah I don't think I am going to send it back, as I don't intend on reselling it. I even like this tag (sans "Length +2") better, as it looks more like the Authentic. But I will talk to the lady and see what she thinks/offers. She didn't think the premier tag changed, but she said I would have gotten a 2011/2012 jersey considering I bought it in November, which she thinks was a special run due to Clay's spike in popularity, and that she may not have gotten the memo about the change. It is amazing to me how Premier/Authentic jerseys (at least for the not super popular players) are sort of limited editions; look for a Clay Matthews premier jersey now, you will be hard-pressed to find one.
It's funny you mentioned the 5; my parents showed it to me on Skype when they received it, and I was super scared as I didn't think the 5 looked right, between the millions of fakes on eBay and even the stock photos having the incorrect font. Then, that Sunday, I looked at all the Packers' jerseys with 5s, and they were all bent like that. Now I find it funny how many fakes I see people wearing on gameday with straight-cornered 5s!
