Having played for Jack in youth baseball, basketball and football, I reflect even to this day on the success achieved then and how that has translated throughout the rest of my life today. The ability to pursue excellence given your desire and heart to achieve it. Nothing is accomplished by just showing up, you have got to want to earn it through devotion of practicing("perfect practice).
He had a great heart and spent as much time as one needed to achieve their best (hitting drills, shooting drills, passing drills, etc).
I wish he could of taught me golf as well as it took me 41 years to hit a hole in one.
David, Jeff, Mark and John and Isabelle, my condolences and prayers are with you all as your father and husband was a great influence on how turned out who I am today. Thank you for sharing his heart.
