Well if I had to compare anybody in wrestling right now to the Rock, it would be the Miz and Anderson.
Off the top of my head, they're the only two heels I can think of that can get the crowd to go along with their catch phrases. Besides Flair and the "Woo." One minute they're booing them, the next they're cheering them along or going along with their catch phrases. Very similar to the Rock when he was a heel.
Anderson's mannerisms remind me more of the Rock. But when the crowd says "Awesome" with the Miz, it reminds me very much of when they would play sing-along with Rocky. When he came out a couple of weeks ago mocking R-Truth, it reminded me of something the Rock would do.
