#2 Samoa Joe

Samoa Joe is in line for a huge push, or at least I hope he is. The former TNA star has all the attributes required of a top star, and he deserves to be in the world title picture. Joe has shown that he takes matters into his own hands to get what he wants and will go any length to get it.
He may not be in WWE title picture anytime soon, considering the title is being held by a heel champion in Daniel Bryan, but we could maybe see him fight for the United States title against Rusev.

Joe could maybe demand more respect and opportunities on SmackDown, which would lead him to Vince McMahon's office and a confrontation between the two could cause Joe to attack McMahon to send him a message and get what he wants.
