"Has the book" is a hilarious smark thing to say about WWE.
There is no "book". There hasn't been a book in WWE for 25 years. There's Vince at the top, Stephanie underneath him, senior producers like Michael Hayes, and a large team of writers.
Like you said before, someone in the back is really smart and knows what (s)he is doing, if that's indeed Trips then I cannot wait for Vince to die
What a gross, shitty thing to say.
As Hunter himself as said many times, NXT is not Raw/Smackdown. It's got a very linear demographic ("smart" to the business adult men), doesn't have all the sponsorship and merch stuff hanging over it and gets to be it's own thing.
It's not like WWE shows would start being booked exactly like NXT.
