I think it works just fine. Go to that RamsNewLook.com site and see all of it together.
Honestly the nitpicking is crazy. The "logo lockup" with the LA/Rams horn logo with 'Rams' spelled out looks good. See it mocked up in their endzones. It's sure as heck better than the 80s when they used to have L and A just jammed inside the word 'Rams'. The 'three stack wordmark' looks nice. The Rams head is in my opinion better than the ugly old one from decades ago.
I'm trying to think what I'd be buying that would just have the standalone logo on it. A polo shirt?
Most importantly- MOST importantly- the 'Rams Royal' and 'Sol' colors are great.
