#2. Seth Rollins - Time for another change for WWE's Messiah?
It isn't unfair to say that WWE did a better job with Seth Rollins' first big heel turn in 2014 than the second one from 2019 (to present). The big difference was that Seth Rollins was on the rise in the first heel run in 2014-2016, while his second one happened while he was already an established Superstar.
Even still, it hasn't been all bad. He put over Kevin Owens and Cesaro in back-to-back WrestleMania appearances - with both matches being memorable and fantastic.
Putting Cesaro over has been the biggest thing Seth Rollins has done on SmackDown. Apart from that, he has been a RAW guy for all of his WWE career. With no signs of a move back to RAW, Seth Rollins needs a big change on SmackDown.
Perhaps a babyface turn would help his WWE run in 2021 and he could end up as a Universal Championship challenger. It feels long overdue, with Seth Rollins' last World Championship success happening in 2019.
