wrestler’s impact on the in-ring product

Scott,
Which wrestlers have had the biggest influence for the in-ring product? For example, Ken Shamrock added "tapping out" and to a lesser degree Flair’s chops. Jimmy Snuka’s high flying? Steiners’ suplexes?

​Shamrock was definitely a big factor in merging in a lot of elements from MMA that are commonplace today. Also, I’d vote for Steve Austin & The Rock, and even Kurt Angle, who essentially created the foundation of WWE Style that persists to this day in the main event. ​
