1. Daniel Bryan
He is no. 1 in this list not because he is the most popular one but because he needs this victory the most. Daniel Bryan was the biggest star of the company before his temporary forced retirement from WWE.
He was the crowd's favorite and would get the loudest cheers wherever he would go. Even after coming back from retirement, he has not missed a single beat. But, he has not been booked according to his stature.
For the most part of the summer, he was booked in a mid-card feud with Big Cass and The Bludgeon Brothers. He has a good storyline going on with the Miz right now, but if he loses against him at Super Show Down, then he would have nowhere to go.
If he could enter in a feud with the Phenom and come out victorious, then he would get back on the right path. He can be booked like an underdog who overcomes the odds against the Undertaker, and I am sure everyone will enjoy that.
