#4 Goldberg and his power moves are iconic
The Spear. The Jackhammer. Those are two moves, especially the Spear, that will be forever linked to Bill Goldberg.
No matter how many people use a spear to finish their opponents (looking at you, Roman Reigns) or a Jackhammer as a regular part of their arsenal (Ryback?), those will always be defined by how Goldberg executed them to perfection.
He may not have been the best wrestler in the world (not by a long shot), especially due to the severe lack of training he received, but he picked up on the little things very well as his career progressed. He has the natural charisma to make everybody stop what they are doing and pay attention to whatever he is doing.
The F-5. The German suplex. Both great moves. Brock has used the F-5 on guys you never could expect could be lifted, and has done the same with his signature suplex. He has basically made it his own. They still cannot be considered iconic, era-defining moves the way Goldberg’s Spear and Jackhammer.
