The economics of Major League Baseball also resulted in the departure of Andre Dawson following the season. Throughout that off-season, MLB owners colluded at the behest of Commissioner Peter Ueberroth to drive salaries for free agents down. Dawson, who should have been one of the most valuable free agents on the market that year, discovered that not only was there little interest in signing him, but that the Expos were publicly commenting about his knee problems in an effort to further drive interest down. Angered by these actions, Dawson walked into the Chicago Cubs' training camp with a signed, blank contract. The Cubs agreed to sign Dawson to a one-year, $500,000 contract, less than half of his previous salary.
