This wouldn't be the case if MLB's biggest stars were getting long in the tooth. But in the last few years, the league's star power has shifted in favor of the youthful. Many stars who are in their prime in 2017 should still be in their prime in 2022.
The aim here is to dive into that question by imagining what a team (a catcher, four infielders, three outfielders, five starting pitchers and one closer) of MLB's brightest superstars will look like five years from now. This will involve weighing present talent, as-yet-untapped upside and potential regression risk of established major leaguers—sorry, no prospects who haven't yet debuted.
