A former MVP gets traded to a playoff contender just before the deadline that allows him to be eligible for the postseason, and of course the rest of the league is going to be upset.
That is the situation with Josh Donaldson, who is currently injured but was still placed on waivers by the Blue Jays and then traded to the Indians on Aug. 31, making him available for Cleveland come the playoffs. The deal drew the ire of American League counterparts, with the Yankees and Red Sox complaining to MLB, according to The Athletic.
