As surprising as Braun's release was, I'm reading that his contract was just too expensive (going to 2023) for what they were getting, so it wasn't surprising.
What I don't get is why they didn't renegotiate - I'm sure he would have taken a pay cut to keep his job.
Riott was a veteran beyond what they gave her credit for. I remember when she had to carry the botching bellas you could literally see her covering up for their mistakes. Unfortunately, Liv wasn't as experienced and even got concussed (while Ruby was never injured by them), which again shows her skill.
Lana, unlike Eva, improved a lot despite not coming from a wrestling background. And getting put through that many table by nia without being injured also says something.
