How much of “Fargo” is Noah Howley and how muc…

Wikipedia lists Noah as the “Creator”, and he and the Coen brothers are all listed as executive producers. It looks like Noah did all the writing for season 1 at least, and probably more.

So what was the Coen’s involvement? How does a show like this work? It’s feels so much like a Coen production, but it also feels so much like a Howley production. Can anyone share some insight into how the creation process works for a show like this, with two sets of “Creatives” who have very distinctive styles?
