Matt isn't going to feud with Orton over the title. He just showed up to get revenge for getting kicked and it just seemed like they were doing something that the fans would like on Monday even though he lost.
About 8-10 months ago I was not a Matt Hardy fan at all and only really liked Jeff. But then I saw Matt live, 4 rows up on SD! and totally changed my opinion of him when he put on a really good match with Finlay. I've come to realize that Matt is, as SP said, much better on the mic(although I always knew that), a much better seller, and doesn't need to rely on high spots to make matches better. I'm all for a Matt Hardy push, but I don't think it'll happen yet. Matt seems to have his shit together though, unlike his brother, so I think we could see him getting pushed within the next year.
