#2 Baron Corbin
Since losing his money In the bank briefcase, Corbin hasn't been used very much on Smackdown Live. When he is used it's usually with a bigger name, such as Shinsuke Nakamura or Bobby Roode. Granted, it wouldn't necessarily a bad thing if he was given a win every so often, I can't remember the last time Baron Corbin won a meaningful match.
Randy Orton and Baron Corbin have rarely crossed paths, making this a fresh match up. Granted, Baron Corbin wasn't able to show much personality outside the ring. A feud with Randy Orton could change that up and hopefully teach Baron Corbin about getting effective heat as a heel. Give these two solid times during the build to Wrestlemania and these two could surprise a lot of people.
