#1 The punt kick
Randy Orton had two amazing finishers - the RKO and the punt kick. While most of the top guys like John Cena, Brock Lesnar, and Roman Reigns have kicked out of RKO, no one has ever kicked out of the punt kick.
Orton most often never connects the move to prevent danger, except in a few cases. However, the possibility of a potential danger forced WWE to scrap the punt kick out of Orton's arsenal. However, with WWE green-lighting Finn Balor's kick to the head from the apron, and other variations of attacks aimed at the temple, it is still unknown why the punt kick is still banned.
Bringing the punt kick back will certainly help the Apex Predator up his game. Nowadays, Orton teases the move often, but ends up being countered by the opponent.
