Not every draft pick, free-agent signing, or trade works out. That's the lay of the land in the NFL. The New York Giants are no strangers to that reality. Think Evan Neal, Devin Singletary, and Darren Waller. All three of those moves have come back to bite Joe Schoen in the you-know-what.
It's just like the saying goes, "You either die a hero, or you live long enough to see yourself become the villain." Meaning, be a general manager long enough, and eventually, bad moves will begin to define your tenure. Look no further than Bill Belichick, who left the best coaching career in NFL history on a sour note, only to go on to coach college football.
