2. Shawn Michaels
WWE.comYes, hes never gone for long but when he does return you know youre going to get a great reaction, a cracking promo and a potential super-kick to the face. Well never see him wrestle again and he seems very happy filming his programmes and being with his family and, obviously, he completely deserves it. When he does make returns though, similar to Jericho, he wants to have a part in something. If Michaels were to return for a cameo you can guarantee that it would be part of the bigger picture. This could obviously link with The Authority but might also be a face-to-face with Lesnar, the man who broke his arm in the Kimura Lock. Either way, Michaels always gives it his all with his brief returns and SummerSlam would definitely benefit. Could it be part of something bigger? Of course. When Michaels has been called in to guest referee matches, he has always been excellent with the story of the match whether it was with The End of an Era WrestleMania match or with Bryan and Orton last year. He is a wrestling legend and, for that alone, to hear his music play at SummerSlam would create a level excitement matched only by who he was going to go face-to-face with.
