Andy Lack and Brian Williams are very good friends and some think that Lack coming back to NBC News will be good news for BriWi.
You can bet that before that it was agreed that Lack would return to NBC, William's future was talked about and decided on.
NBCUniversal boss Steve Burke suspended Williams, and Burke will be the one to decide if and when the anchor returns.
There is no way NBC hired Lack and did not discuss what the plans with Williams will be? Whether Williams returns or not, you can bet that it has already been decided and Andy Lack knows exactly what that decission is.
For the rest of us, we'll just have to wait and see.
