#1 Worst: The botches
So, it's one thing that WWE introduced The Viking Experience last week and then already changed their names to The Viking Raiders. But then, the commentators were so confused while calling their match that they alternated between calling them both names through the course of the contest.
Moreover, shouldn't Cesaro be walking out to his own music, now that The Bar has split up? He walked out to Sheamus' music much to the puzzlement and the amusement of the WWE Universe, this week.
Moreover, Mike Rome had one of those moments where he forgot that The IIconics were two people and not one. So he referred to them by one name, namely Peyton Billie Kay.
These are not even errors that were made by the performers but those in the non-competing roster, who I'm sure got an earful from Vince McMahon and Kevin Dunn shortly afterwards.
