Grant Garland Teaff (/ˈtæf/; born November 12, 1933) is a former American football player and coach.

Teaff began his head coaching career at McMurry in 1960, serving there until 1965.

To compensate for the loss of healthy players, Teaff introduced what is now known as the Wildcat formation.

One was an excellent fisherman, reeling in one catch after another, while the other couldn't land a single fish.

With this story, the coach let his team know that winning may cause momentary discomfort, but if they were able to put that aside for 60 minutes, the end result would be worth it.

His Baylor teams were notable for success against the University of Texas, finishing with a 10–11 record against the Longhorns, including the game during his final season where he got one last win in the series by a 21-20 margin.

The AFCA represents coaches across the United States and is often consulted by the NCAA and the media regarding rule changes and developments that take place in college football.
