In a typical baseball offseason, even the biggest personnel moves are fundamentally simple equations: Team X signs Player Y to a $ZZZ million contract (as will likely be the case for J.D. Martinez this winter), or a small-market team trades the superstar it can no longer afford to a large-market team that can (as may be the case with Giancarlo Stanton) for prospects and hope. But this winter, the most intriguing transaction on the talent marketplace will require something closer to advanced calculus to close out.
