Rewatched an old master copy of a 1974 Cowboys-Raiders game on YouTube (worth googling) - 1. I'd forgotten how great Cosell was. Arrogant, of course - but more often than not, absolutely correct with his facts. 2. Gifford was really bad with play by play, not sure he had a bad spotter (missed names) or not (I think his spotter was future TV exec Terry O'Neil), but describing the end of the third quarter as the first? Weird. 3. Alex Karras probably tried too hard to replace Gifford, but he worked well in the booth. (Prescient Cosell comment during the broadcast - "I don't think people realize that John Madden is really a funny guy, I'm surprised nobody's tried to bring that out of him more.").
I wish the hot take artists working today were half as correct as Cosell was. He really should be honored by Canton. Shoot, the honored a guy who made his career doing a half-assed impression of the guy.
