Marvin Bagley III was born March 14, 1999, in Tempe, Arizona. The bloodline ran deep: his grandfather was Joe Caldwell — “Jumpin’ Joe” — the #2 overall pick in the 1964 NBA Draft and an Olympic basketball player. His father, Marvin Jr., grew up in Durham, North Carolina, played football at North Carolina A&T and professionally for the Arizona Rattlers. In Arizona, Marvin Jr. met Tracy Caldwell — Joe’s daughter — and started a family.
Young Marvin was 6’5 in middle school. He briefly played quarterback until a large boy wearing #99 body-slammed him from behind in a game in the rain. “That was the day I was like, ‘I don’t think football is for me.’”
His high school journey covered three schools and two states. Freshman at Corona del Sol (Tempe): state champion, MaxPreps National Freshman of the Year. Sophomore at Hillcrest Prep (Phoenix): teammates with Deandre Ayton. Then Sierra Canyon (Chatsworth, CA): sat out a year, then averaged 24.9/10.1. California Gatorade POY. Consensus #1 recruit in the Class of 2018.
Then the earthquake: in August 2017, Bagley announced on SportsCenter that he’d reclassified from 2018 to 2017, pulling Danny Ferry’s retired #35 Duke jersey from a bag on live television. “That’s what Coach K preached — the brotherhood.” Vegas odds for Duke winning the title shifted from 7-1 to 3-1 instantly. His father, from Durham: “You just got to go with your heart. And that’s where his heart is, at Duke, in the Bull City.” Duke first offered him a scholarship in ninth grade.
