Her contract may require that her show have a certain ratings number and total viewership for her to collect her total salary, benchmarks , etc.
I doubt that NBC is stupid enough to pay her 23 million a year with no requirements on the success of her show.
You never know if they hired "hip" youngin's to negotiate. Or, people that eschew history, aka learning from the bombs that were "Chevy Chase", "Magic Johnson", "Joan Rivers", yadda yadda yadda.
THAT would be icing on the cake!...........................
