#4 Seth Rollins (WWE SmackDown)
Seth Rollins has emerged as one of the backbones of WWE in the last decade. Debuting on the main roster as part of The Shield in 2012, Seth Rollins has had a highly successful career so far, having won both the WWE and Universal Championships twice.
While he is considered one of the best in-ring workers on WWE's current roster, he also has been on the receiving end of some massive heat and even being called dangerous. After Seth Rollins broke John Cena's nose during an episode of RAW with a misplaced knee kick, WWE Hall of Famer Bret Hart bashed him for being reckless.
Will John Cena beat Ric Flair's record? A former WCW Champion thinks so HERE
"He [Rollins] knees him the face so hard, and so recklessly, and so dangerously. He could easily kill somebody with a knee like that to the face. It's a testimony to John Cena. A, he finished the match and B, that he didn't get a shotgun and shoot Seth Rollins when he came through the curtain."
Seth Rollins has faced similar criticism due to one of his moves - the turnbuckle powerbomb, aka the Buckle Bomb. It was this move that injured Finn Balor during his Universal Championship match against Rollins at SummerSlam 2016. WWE Hall of Famer Sting also suffered an injury due to the same move at the hands of Rollins at WWE Night of Champions 2015.
