Go back and watch Nash's promo on Flair, where he calls Flair and the "old boys" out on leaving potholes in the road they supposably paved for them. It's an excellent showcase of bnot only how good Nash could be if given the right angle/stage to showcase his talent on, but on how over he legitimately was (compared to Waltman who opened up the promo).
Trust me man, Nash is overated.
I think you've confused the term overated with talented. Whilst Nash may not be as talented as Triple H, he hasn't gotten the bazzilion title reigns either.
You'll notice how I put Jericho in there. Jericho is one of my favourite wrestlers...but I prefer him in the midcard. I find him far more entertaining, and he gets a bit mroe freedom without having to conform to the boring, run of the mill, slow talking promo skills which WWE imposes on their main eventers.
