Push Rollins. If they truly commit to him as a babyface, he could work. Dude has the best in-ring storytelling ability of the three which makes him the best option for main events.
Bury Owens. I actually like Owens so this is a bit harsh but it wouldn't be a bad thing if he took a few steps down the card and reinvented himself somewhat. He's been this character since his NXT debut and he needs to freshen it up to remain relevant in the future.
Release Balor. No mic ability, no in-ring psychology and not a very impressive wrestler either. Keep his gimmick by having the Demon possess another wrestler (one who actually is worth a damn) and make a real star.
