Sheamus holds the Money in the Bank briefcase, and could be miffed that he was left out of tournament consideration. Thus, Sheamus merely inserting himself into the final match is more than possible. Sheamus then winning the championship without even entering the tournament keeps him a heel and gives him some steam early in a title reign. Is Sheamus vs. Reigns at say, Royal Rumble, with Reigns winning via some sort of funky thing happening in the match to Sheamus something that could occur? Indeed. Will it? Probably not, but we're definitely exploring all options here.
