It is so statistically unlikely as to be almost unbelievable. Somehow, the Gronkowski family has produced three sons who play in the NFL (Rob, Chris, and Dan), one who was drafted into Major League Baseball (Gordie, Jr.), and another who is the starting fullback for Kansas State (Goose). Their father, Gordy, even played college football for Syracuse.

How did it happen? From an early age, Gordy realized the potential his sons had and worked with them to make the most of it. Beyond their monstrous size, physicality, and raw talent, he instilled in them a commitment to fitness, health, drive, and determination that would give his boys a leg up in ways other families simply couldn't match. And the boys' motivation certainly wasn't something solely triggered by a driven father. They were like a pack of adolescent wolves readying themselves for the recruiting hunt. Still, all were honor roll students; the three oldest earned college degrees. Each was motivated and inspired by his brothers. Competition and bragging rights were -- and continue to be -- a big part of what makes the Gronkowskis tick. "Growing Up Gronk "reveals the secrets to the Gronkowski's astonishing collective success while opening the door to a lively, entertaining, one-of-a-kind household.
