There's a huge divide in WWE creative that's resulted in something of a storytelling stalemate. Part of the team wants to select a few talents to push, creating stars as big as Taker, Bryan, and Cena. Another group doesn't want to do that, as they feel it would limit storytelling options. None of them want to see anybody get over by his/herself, though. That's why they kept trying (and failing) to bury Bryan. That's what just recently happened to Cesaro. It's only a matter of time until they do it to Sasha Banks. Nobody gets over without Creative deciding it happens, but Creative doesn't seem to want anybody to get over.
Now we've got a bland product that's basically a full mid-card, and no clear #1 contender that the fans really want to see dethrone Rollins, who Creative has done their best to ruin. They trot him out to say the same thing to open every Raw, put him in the same basic premise for each title defense - "you can't win on your own." They took his Curb-Stomp due to the concussion lawsuits, and they gave him the Pedigree, which, let's face it, has always looked like a weak finisher.
Blame Creative, and blame Vince, who refuses to break that stalemate.
