Sorry Will but I disagree with that completely.
If the purpose of Sheamus winning the King of the Ring was to put John Morrison into the Main Event, then why not just have him win the tournament? Being King of the Ring would help him more than just making it to the finals.
Morrison could have used the title of King of the Ring to get him into the Main Event picture more than Sheamus, who already is considered on that level.
Not true. There have been several names to go through the King of the Ring tournaments, and come out losing in the Finals - yet still become more impactful because of their involvement.
These four instantly come to mind, and I'll toss in a bit on why.
1994: Razor Ramon: He lost to Owen Hart, yet went on to have arguably a more successful career. He'd only gotten one Heavyweight Championship match, at the 93 Rumble. But after this KotR run, he was back in the running as a top name in the Company.
Owen is pretty much one of only 2 guys (Mabel being the other) to take the KotR victory and make it work as apart of his character. So Ramon isn't a great first choice, but it still counts.
1995: Savio Vega: This is probably one of the best ones to use. Let's face it, Vega was pure shit. But his tournament run on this night was big for him. It pretty much was his debut, and more importantly put him on the map as being someone to contend with.
Sure, he never became a Main Eventer, persay - but facing everyone he did, only added credibility to his name and made him someone to consider as a star instead of a jobber.
1998: The Rock: Another similar case to Ramon, but Rock was a runner-up. Let's keep in mind, Rock wasn't a true star at this point. His KotR run wasn't even what people wanted. They wanted Dan Severn v. Ken Shamrock, and Rock spoiled it.
It was this, that ultimately put him into the next level to face guys like Shamrock, and Mankind, in the Main Event - and go on to win the next tournament he'd be put in; at Survivor Series later that same year.
2000: Rikishi: Kurt Angle was heavily favored, but Rikishi making it all the way to the finals, beginning with a (albeit DQ) victory over Benoit, then putting up a good match with Angle - it created the "next level" for Rikishi.
Who, as we know, would later go on to be the guy who "dun'it".
All of this, is why I believe John Morrison was put over more than the actual winner - in his losing effort. Morrison has been pushed, briefly, like a Ramon or a Rock; but perhaps it was this Tournament run that will help repush him into the Main Event scene to prove he has the stamina and longevity to go up against tougher opponents.. like an Alberto Del Rio, or more specifically a Sheamus.
