Saying goodbye is never easy.
Especially when you're quarterback Eli Manning and Head Coach Tom Coughlin.
Through it all, Coughlin has had Eli's back and treated him like one of his own.
With this strong bond intact, they've battled together for 11 years in the NFL, through the good times and tough times.
The good times came when the New York Giants won Superbowls in 2007 and 2011.
The bad times came when the team failed to make it to the postseason over the last three years.
In the past, there was always the promise of "next year,' or "we'll get them next time," or "we just have to go back to the drawing board and figure it out."
However, there won't be a "next year" in 2016, at least not for Tom Coughlin.
The 69-year-old chose to resign as Head Coach of the New York Football Giants after the final game this past Sunday.
Before Coughlin officially stepped down though, he let his son and quarterback know in a bit of "Good Will Hunting Moment," that it wasn't his fault for the way things ultimately ended.
Normally stoic and unemotional, Eli tried as hard as he could to keep the tears back through his coaches emotional words, but couldn't hold back as he watched the only coach he has ever had in the NFL ride off into the sunset.
