The thing is nobody should really be asking him to put over people or have a good match at this stage. I don't really think anyone is really going to gain anything from beating him now anyway, a lot of that credibility is over and chances are the quality of the match will diminish the winner in the eyes of most of the audience anyway, and with the roster they have they shouldn't need to rely on him to carry the show in terms of quality matches.
Just let him come in, do his entrance, hit a chokeslam, stick his tongue out and go home. He gets paid, the fans get to see the entrance and it becomes part of the legacy and tradition. I know someone will moan about him destroying the young guys but it's not like they don't have guys on the roster that they don't really have plans for.
