WrestleMania 28 is Sheamus' chance to show that he has what it takes to be one of the WWE's top guys.
There's no denying that Sheamus is talented. He's good on the mic, despite his goofy Irish accent. He also has an intimidating physique, despite his pasty white skin.
The WWE built up Sheamus the exact same way they try to build up most new guys—squash some of the lower card wrestlers for a few months, before moving on to a higher-profile rivalry.
Often times, wrestlers that are built up this way fail. They either can't get over with the crowd or they fail to impress management. For every success like Sheamus, there's a Heidenreich or a Gene Snitsky.
The fact that Sheamus has gotten over with the crowd is very impressive. He's shown over the course of the past few years that he's not a flash in the pan. But while Sheamus has shown that he's a legitimate wrestler, is he ready to carry the WWE's biggest pay-per-view of the year—WrestleMania?
WrestleMania 28 has the potential to be the best WrestleMania ever. The Rock vs. John Cena is a dream match in terms of history and money making. The Hell in the Cell will be nice because it's between two of the best WrestleMania performers of all time—the Undertaker and Triple H.
The WWE championship match will most likely be the best "wrestling" match, in terms of in-ring talent. Chris Jericho and CM Punk are stellar in-ring workers.
Then there's the Heavyweight championship match between lesser-known stars Sheamus and Daniel Bryan. Of all four main matches at WrestleMania 28, there's no doubt that this is the least talked about. It's also why this match could be a pleasant surprise. Bryan is one of the top three in-ring workers in the WWE. He has never put on a bad match in his life.
Who will win the world heavyweight championship?
Sheamus is also ready for this opportunity. He's no stranger to WrestleMania. At WrestleMania XXVI, he faced Triple H. The rivalry eventually led to Triple H being written off TV for 10 months. Working with Bryan at WrestleMania will make Sheamus' life easier. This isn't just Sheamus' chance to carry the biggest show of the year; it's Bryan's chance as well.
Triple H has been behind Sheamus' push since 2009. The entire WWE seems to agree with Triple H, giving Sheamus a historic victory at the 2012 Royal Rumble. Winning the Royal Rumble is the ultimate sign of approval from the WWE. All the great ones have won one—Triple H, Undertaker, John Cena, "Stone Cold" Steve Austin, etc.
WrestleMania 28 will be the most important match in Sheamus' career. It's his chance to go from a valued midcard performer to a routine main eventer. To this point, all Sheamus has done is give the WWE reasons to believe in him as a top guy. This is his chance—one that he will capitalize on to cement his status as a top guy in the WWE.
