Regardless of whether a team is a perennial World Series contender, a fringe playoff team or a cellar-dweller, there is always at least some reason for excitement looking ahead to the future.
Whether it is a single player destined for stardom or a deep minor-league system overflowing with talent, the "next big thing" is always waiting just around the corner to step in and make a huge impact. Granted, the next big thing doesn't always pan out as hoped, but they give fans a reason for optimism nonetheless.
