I watched Dallas and Carolina too. The Cowboys definitely miss Frederick at center but to me their biggest issue is lacking WRs and TEs that can get separation. They need to scheme guys open but yesterday they just spread everyone out and told them to go win one on one. And they could not. I like Allen Hurns and loved their pick of Michael Gallup but those guys need much more creativity to get open.
I think it is time to just accept Cam Newton for what he is- a great athlete who is a better runner than passer. You either let him play that way or go to someone else. He is not going to play to 36+ that way but he is what he is.
