Tom Coughlin has helped the Jacksonville Jaguars rebuild a roster in his image, with a physical identity, strong run game, excellent defensive line, and an improving offensive line -- and he's done it in one offseason.

Coughlin is certainly happy now, but he wasn't very happy back in 2015 when the New York Giants decided it was time to move on from him as head coach. At the time, it was believed that Coughlin was unhappy with being removed from the role after failing to consistently win with a roster general manager Jerry Reese had built. According to Gary Myers of The Daily News, Coughlin wasn't just unhappy about being removed as head coach.

In a recent column, Myers broke down a little-known secret about Coughlin's departure:

One of the worst kept secrets in the NFL is Coughlin was not only upset at being fired, but he was incensed that Reese, who was responsible for providing him the players, wasn’t fired with him.

On Wednesday, just one day before this column surfaced, we broke down in detail why Reese should have been fired and Coughlin should have taken over as general manager after the 2015 season when he was removed as head coach.

Deciding to completely cut ties with Coughlin from the Giants organization, and to continue forward with a general manager in Reese -- who had not made the playoffs once since the 2011 Super Bowl season -- was where ownership failed the fans.

In 2017, the Giants will miss the playoffs for the seventh time in nine years with Reese as their general manager. They will also miss the playoffs for the sixth time in seven years since the 2011 Super Bowl that Reese supporters continue to cling to. Despite the fact that Reese was gifted a franchise quarterback before he ever accepted the job, something some general managers search for their entire tenure, these are his results.
