Austin saved the WWF for a period of about 2 1/2 years or so before Rock took over, but neither of them combined were on top as long, for better or worse, as Cena has been. If someone else had come down the pipe who could compete w/ Cena's popularity, I'm SURE we would've seen them pushed in a similar fashion much like how Rock/Austin existed as mega stars simultaneously. But there's nobody there(maybe Bryan has a chance), which lends to Cena's importance even more; so much so that they can't even really take a chance to turn him heel.
Again, you won't catch me cheering for the guy or even watching a whole match of his, but he's pretty much put the team on his back.
