If I were to name my Mount Rushmore, Kurt Angle would be on it.
Edit: Now, that doesn't mean that I don't find Chad Gable awesome, I really do. But, I absolutely agree, Kurt Angle was a beast.
Edit: To complete the Mount Rushmore, I'd go with Steve Austin, Bret Hart and Eddie Guerrero. My 4th one used to be Chris Benoit, but he forever destroyed his legacy with what he did.
