It pretty much always has been. Smackdown, even during the brand split, was always made to have it's balls chopped off when it was getting obviously better than RAW. Now, without the distinct brand separation, there is little reason to tune in. Nothing ever happens. I hope it's just in a funk while the creative team gets used to a third hour of RAW, but my gut tells me it's not lol.
It was in a funk far before the 3rd hour of RAW started.
