โMark Harmon Almost Became an NFL Quarterback Before NCIS Fame!โ
Before becoming the iconic Leroy Jethro Gibbs on NCIS, Mark Harmon was poised for a career in the NFL as a quarterback. Best known for his role on the show, which he played for 19 seasons starting in 2003, Harmon recently made headlines with cameos in the NCIS: Origins spinoff, featuring a young Leroy Jethro Gibbs.
What many donโt know is that Harmonโs football background runs deep. His father, Tom Harmon, was a Heisman Trophy winner and broadcaster, which gave Mark a strong football foundation before he turned to acting.
