To go off on something of a tangent, I dislike how Swagger is the poster child for how being "hotshotted" to the title can go wrong.
First thing's first, guys like Kurt Angle and Brock Lesnar won their first world championships in less time. There is nothing inherently bad about a sudden push. Quality writing and quality talent can make it work, and have made it work.
Second thing's second, Swagger's reign was actually rather good. It was a little bit chaotic and lacking direction but there are some hidden gems in there and Swagger upheld his end of the bargain admirably. Some solid little feuds - and matches - with Big Show, Morrison, Orton, Jericho, Edge, and Mysterio. Some of the state of the championship addresses drew major heat. It even featured, and this will be about the fiftieth time I've brought it up, what was one of the best promos of the year - the trophy promo. The myth that Swagger 'wasn't ready' for the title seems to stem from him being given no material to work with after his reign was over. He was allowed to fade into obscurity; he was encouraged to fade into obscurity. The reign itself was good, if a little rough around the edges, and Swagger did great with what he what he was given.
As far as I'm concerned, Jack Swagger is a good wrestler, capable of good matches and good promos, with a good character, and still some potential to realise if he's nurtured properly. His reign with the world heavyweight championship is an argument for sudden elevation, not against it.
