INDIANAPOLIS--This Sunday is Father's Day and for those all over the world, the day hits home on all sorts of levels.[
Monday Morning Quarterback talked with a dozen NFL people](http://mmqb.si.com/2014/06/12/nfl-fathers-day-life-lessons-the-mmqb/) for the best thing they've learned from their dad.
Colts GM Ryan Grigson shared his thoughts to MMQB on what his dad meant to him.
Jeffrey F. Grigson taught me to never feel sorry for myself, and how to fight for those you love. My father was a 6-foot-3, 250-pound former Marine, college defensive tackle and construction worker. To me, he looked like the Incredible Hulk. I lost him to brain cancer when I was 9, and yet, I still have many fond memories of him. He still found the energy to help coach my first football team, referee my basketball games and take me and my friends to the movies and the park. He never stopped being a dad. Years after his passing, I asked my mom if he ever had any weak moments with her. She said he never once complained or ever even said, "Why me?" The example he demonstrated in the face of severe adversity has given me strength whenever I've encountered challenges. My father only lived to 33, but in our nine years together he gave me plenty of vivid examples of what it means to be both a father and a man.
