DiGiorgio pursued his teaching certification at Saginaw Valley, stating that "(NFL) stands for 'Not For Long' -- instead of the National Football League -- because careers don't last long in the NFL. John DiGiorgio was a student teacher at Siebert Elementary School in Midland. DiGiorgio, a former All-American at Saginaw Valley State University, helped out Bob Wellman in his physical education classes. He also delivered big hits that drew fans to create catch phrase for his incredibly astonishing, punishing, blows delivered to opposing players: "It's not delivery, it's Digiorgio!" During the 2008 off-season, DiGiorgio began to student-teach physical education at Siebert Elementary in Midland, Michigan.
