Times have changed.

I still couldn't have won it

Are you sure she had a much more graceful landing?

......I'm having a hard time seeing what's more graceful about it.
Is it because she stands more slowly? Cause the "perfect landing" would be sticking the landing. With her knees bent so much, and taking so long to stand, that would be slaughtered by today's judges. Mckayla Maroney's landing was nearly stuck, quick, and concise.

50 years from now, these people will do like 10 flips

Believe me, it's hard to do; even the first one is.

I was in gymnastics as a child, and that first one was the second routine we learned for the vault.

Her final vault wasn't as good, but this is the one that qualified her to go on
If this had been in the final round, she would've won, no doubt

Well can you do a full 360 degree flip with your body straight and land on your both feet?

3 full flips
