As soon as the Cubs clinch that last win, 5 million people will immediately descend upon Wrigleyville, they project. Based on data from the Red Sox's 86-year-drought-breaking World Series win in 2004, that figure comes from the Red Sox victory parade crowd of 3.2 million, multiplied by how much longer the Cubs' drought has been than Boston's was at the time of their win (126 percent longer, or a 26 percent increase, to be exact). Adjust for population, as Chicago's is about four times larger than Boston's, and you end up at a whopping 5 million people and change.
