I am willing to entertain (though not fully believe) that a hoax is possible. Your the Browns, the team that screws up everything including the recent over-promising on the logo fiasco. Not hard to get the media and assorted media wanna-be's to bite on the leaks. Its the Browns, of course they sent to new uni's out early because that is what the Browns would do. Minimal investment to stock a couple shelves, get some photos out on social media with the fakes. Then at the big reveal you drop the hammer. Story becomes the hoax and if the uniforms exceed expectations you have a PR coup.
If these are the new uni's then I am disappointed though not distraught. Here is the thing about change...it requires CHANGE. This half assed redesign in the guise of holding onto tradition really pleases nobody. The supposed "new" uni's while the slightest of upgrades from the prior design reflect an organization unwilling to chart a new course, just meandering on the fringes of mediocrity.
