The Marino is really bad.
The first thing that sticks out is how shiny the material is. The shoulders and sleeves should have the same sheen as the Moss. Also the side panels should be spandex, not the same shiny material. There also should be no gap between the NFL equipment patch on the neck and the mesh body of the jersey.
Looking at the jocktag on the bottom, Reebok never printed "Players Inc." in red. Also the NFL logo is terrible.
Authentic jerseys do not have a drop tail. Meaning the back should not be longer than the front.
The material that the numbers are made of on an authentic is called tackle twill which is thick, stiff and almost cardboard like. It also has a flat look, not shiny like this one. The numbers also should not be bubbled up.
The Peterson has many of the same issues. Also the retail tag should not be attached with a plastic loop. It also has the wrong hologram, it should be square not round. The NFL equipment logo on the neck is very poor and cut badly. On top of all that, The Vikings have never worn that jersey. It seems to be the love child of the the older style and the newer style. It has the sleeve logos and body of the early 2000's and the wordmark under the neck and number font of the newer style.
That should about cover it.
