Some of those come off as decent, and some just look like shit. The Patriots one just looks horrible. Also I don't think they are bringing back the old Buccaneer's symbol. Also people in the comments are saying those pictures are old fakes.
The shorts look so fucking stupid. Some of the jersey designs look cool but the actual construction of the uniforms (especially the shorts, I can't stress that enough) looks incredibly awkward. Maybe they'll look better in real life, but the rendered versions look like shit.
