What wrestler has improved most this year, IYO?

The Miz. He has improved far from the beginning of the year, let alone his career. I hated him in the beginning of the year because he had the mic skills but no in ring talent while Morrison should have been where Miz was. I still say Morrison deserved Miz's push but Miz has also earned what he has gotten and I am looking forward to him becoming WWE Champion.
