Is there some reason to think Murphy will be out after 2024? It's not like he has a fixed term or anything. And a "completely new team"? I VERY much doubt that - too much good young talent, plus it would be stupidly contrary to the Packer way of doing things.
I agree, way too early to extend Love, just as it's way too early and also very wrongheaded to be down on him and his performance. The only possible reason to extend him now would be kinda a leap of faith to sign him now for a bargain price - and I doubt that happens.
