#2 Samoa Joe

'The Samoan Submission Machine' has been out of action since January this year. He had suffered a foot injury in his match on Raw. Joe has been in the title picture since his debut on Raw but never being able to capture it. His feud with Roman Reigns had a lot of potential, but he ended up injured before it could really take off. He kept feuding with The Shield along with The Bar on his side. His return date hasn't been confirmed yet but the day he does return, expect him to throw bodies all over the place.
Samoa Joe and Dean Ambrose have faced each other in a singles match on Raw before but there was quite a bit of interference from Jason Jordan. The two of them have never gotten a chance to really go at it in the WWE ring. With Joe's strength and Ambrose's acrobatic stints, the WWE Universe would definitely be kept on the edge of their seats for this one. Samoa Joe can hit hard and Dean Ambrose knows how to take a beating and come back fighting. Expect this match to be what good old JR would call a "Slobber Knocker".
