Kane has used this move for much of his career, but with the demon once again handing in his mask and getting up there in age, he likely doesnt have much time left with the company. Reigns could adopt the move now that Kane will no longer be using it as a signature move. The sidewalk slam is easy to execute, looks incredibly painful when performed by a large superstar such as Reigns, and would complement the physical moves that currently comprise Romans arsenal.
