I like this route. I think they should do something along the lines of a Bret/Austin feud. Have Orton turn heel and have Orton and Sheamus have a match or two. The crowd will obviously side with Orton, and then creative can do something creative and have Sheamus be visually frustrated by the crowd not siding with him. Have him turn heel and have him do so because he upset with the fans for not siding with him. That, and have Orton become a tweener face. That's what'd I'd do.
And if we're lucky we'll get a 20-minute promo about the "WWE Universe turning their back on him" and "respect."
