NBC does a great job with the US Open. I enjoy Miller, and I think Rolfing and Maltbie are two of the best on-course reporters in golf, along with Feherty. I enjoy Gary Koch as well. I guess NBC will still have the Players, Florida swing and FedEx Cup.
As for who would be in the booth, I would not be surprised if Thom Brennaman is the host. He's been rising up the network and is their #1 college football guy. I would also not be surprised if they try and go after Miller to do what Faldo does and do a two-network stint....but let's not forget Miller is getting up there in age and may be ready to hang it up soon. This may be a way for him to go into the sunset. Other options for analyst would probably include David Duval, Tom Watson and Colin Montgomerie, who have some TV experience.
