Cody sold me way back when he wore the protective mask. That was a terrible gimmick that he knocked out of the park on charisma alone. I said then I wanted to see him and Ziggler main event Wrestlemania in a few of years.
The rise of Daniel Bryan has changed the landscape since then, but Ziggler and Rhodes are still both critically underutilized. They should be much farther along on the path to main-eventing Wrestlemania.
Regardless of how we all feel about them now, years ago, I'm sure many of us (myself included) felt that Cena and Orton were going to become the future top guys, and were excited when it actually happened. Of course, the reason it happened is because there was a very clear "changing of the guard," a vacuum at the top left by the departure of guys like Austin and Rock, that demanded to be filled. If that hadn't happened, Cena and Orton would have been the Ziggler and Rhodes of their day, I think. Underutilized.
Now there is no such vacuum, and that's what's making it so easy for Vince to keep guys like Ziggler and Rhodes in the midcard. If something doesn't force the issue, he'll never clue in to the talent he's sitting on.
