Risk is the nature of the beast in Major League Baseball's free agency, especially with regard to the players at the top of the market. For every Max Scherzer and Bryce Harper, there's an Albert Pujols and Pablo Sandoval.
On the 2021-22 market, the players with the biggest boom-or-bust potential aren't hard to spot.
There are six in particular we want to talk about. Lest anyone get too hung up on the "bust" element of this exercise, please note we're not trying to characterize these guys as being doomed to fail. They're indeed very good players, but who are also inherently risky based on factors such as old age and flawed abilities.
