Jericho, Benoit and Angle were similarly held back by politics and Austin/Undertaker's refusal to put anyone new over. I mean who'd Austin ever put over cleanly? He gave The Rock a win years after his prime had ended as a 'thanks for letting me kick your ass and win every other match conclusively' consolation prize.
If the internet was this big in 1999, people would be asking why Austin was making Foley look like a jobber every time they fought.
I don't think Benoit is a great example, but people like Angle got over because they were developed in the midcard. There's really no midcard today worth talking about. Stars like Edge and Angle blew up and got to main event status wrestling each other. They didn't need rubs from Austin.
Who can legit give someone like Ziggler a boost today? Sheamus?
