10. "The Midnight Massacre"

Dumbass Move By: Joe McDonald and the New York mets

Tom Seaver must've overstayed his welcome in New York. What other reason is there for why the Mets couldn't cough up the extra dough to keep Seaver in blue and orange? On that horrible day known as "The Midnight Massacre," New York traded their best pitcher (three-time Cy Young Award winner) to Cincinnati for four mediocre players. Seaver, who was 7-3 at the time, finished the season at 21-6. Does it make it any crazier that the Mets made Joe McDonald the team Vice President two years after this move? Actually, considering it's the Mets it makes perfect sense.
