Joe Gibbs himself comes from the Don Coryell "tree" (which was an offshoot of the Sid Gillman "tree").

Joe Gibbs had some great OFFENSIVE assistants, that would go under his "coaching tree" (some went on to become Head Coaches in the NFL). Joe Gibb's offensive ball control system is run by more colleges and professional teams than the "west coast", "vertical passing game", or "run and shoot" systems. Many of the coaches below spread it around the league AFTER working under Gibbs:

1. Don Breaux
2. Dan Henning
3. Joe Bugel
4. Jim Hanifan
5. Warren Simmons
6. Jack Burns
7. Jerry Rhome
8. Rod Dowhower
9. Charlie Taylor
10. Earnest Byner
11. Stan Hixon
12. Al Saunders
13. Russ Grimm
14. Joe Jacoby (now coaching in college)

NOTE: There are others - these are just the ones that come to mind.
