 No matter how abrasive the relationship between Seaver and his employers had become, dealing him away was a serious miscalculation, and Shea Stadium became known as "Grant's Tomb" in the New York sports pages.Grant did acquire some good, young talent for Seaver; Flynn was a slick fielding second baseman who won the NL Gold Glove award in 1980, Zachry was co-winner of the NL Rookie of the Year award with Butch Metzger the previous season (coincidentally, they would be teammates on the Mets in 1978), and Henderson would be narrowly eclipsed by the Montreal Expos' Andre Dawson for the award in 1977.Dave Kingman was in the final year of his contract, and thus, would have become a free agent at the end of the season unless the club re-signed him, but coming on top of the Seaver trade, aligned with the fact that the team got very little in return for their big buster, the Kingman trade only added to the growing disenchantment at Shea Stadium, and June 15, 1977, would forever be known to Mets fans as "The Midnight Massacre."
