I don't think people understand what GOAT means, it's ONE person, you can't be "a GOAT", you can only be "The GOAT". As for Sheamus, he's going to be big by the end of his career, without a doubt, from the way he's getting over to the way the company are protecting him. From Summerslam live reports, the line for Sheamus' table at Axxess was the biggest and people on RAW were surprised by the reaction he got, saying that the fans are now seeing him as a big time star on the level of Cena and Orton and his pop rivaled them. He's a successful project and is only 3 years in the company. But the GOAT? No. For him to be the Greatest Of All Time, he needs to transcend the industry like no other, to become bigger than the business, to sell out stadiums with a facial expression, to bring rare magic every time he opens his mouth, to have that once in a lifetime charisma that can captivate and turn every head in any room. To be bigger than Maradona, bigger than Jordan, bigger than Jackson, bigger than Ali, bigger than The Rock, and that's not happening, not with him and not with anyone else.
Yeah, right. Sheamus is not even on the same level as Punk, let alone Cena. He might reach Orton's level, but then again, his stock is falling rapidly anyway.
