From 1994 all the way to 1996 when he would walk away from the company to move back to the WCW and formed the NWO. Nash would become a triple crown champion in the WWE as he would hold the Intercontinental, World, and Tag Team titles. However, Nash would help change wrestling when he jumped to WCW with Scott Hall to form the NWO with Hulk Hogan and set WCW up for a crazy run.
Overall, Kevin does deserve to not only be in the WWE Hall of Fame, but based on his legacy in wrestling he deserves at least to be a two time inductee from his NWO association. At one point Kevin was destined to be the top star of the future for the WWE, but then became legend instead just by walking out on Nitro. In my opinion Kevin made an impact because still today people notice him and cheer when he comes out on the show which means he did something right.
