This is the best Rams concept that I've seen. I disagree with a couple of posters that the white pants need yellow added or that the yellow pants need the white stripe. There is no other white on the entire home uniform, why would you add a color that has no place? The single pants stripe also adds continuity to the sleep stripe and the the Ram horn on the helmet. The horns also have no place on a modern uniform cut. The current throwback is fine for nostalgia, but that sleeve horn looks nothing like a horn anymore.
And the this may be blasphemous as somebody that has been screaming for the return of royal/yellow, but I think I may actually like the navy concept better.
The logo, I'm not as big of a fan of. It's close, but something is missing. I've struggled trying to come up with a way to integrate the Horn, and the LA in side the Rams, but I haven't been able to make it work. yet
