George W. "Dad" Gregory (April 19, 1879– September 6, 1946) was an American football player, coach and lawyer.

Michigan's football team was recognized as national champions for each of the three years in which Gregory was the starting center.

At the time of the 1880 United States Census, Gregory at age one was living in Lincoln, Placer County, California with his parents and three older sisters, Alameda, Cora and Louise.

Pressure was placed on Gregory to remain at Stanford, but he opted to move east with Coach Yost.

During a 128–0 victory over Buffalo in 1901, Gregory reportedly asked for an opportunity to run the ball for a touchdown.

"[10] A profile of Gregory in the 1903 University of Michigan yearbook noted:"While not an exceptionally heavy man, his build attracted early in the fall of 1901 ... Yost tried him at center and he developed rapidly.

"[11][12]Prior to the start of the 1903 season, press reports indicated that Gregory and halfback Willie Heston, both of whom had come to Michigan from California with Coach Yost in 1901, might not return to the team.

[13] In 1903, Gregory was identified as the distributor of "Hurry Up Yost Cigars" in advertising published in various University of Michigan publications.

One publication noted: "The College has secured as football coach 'Dad' Gregory, of the University of Michigan.

"[20] In the letter, Jordan accused Gregory of having accepted money to play football at Michigan and of having flunked out of Stanford.

Jordan stated:"I referred to [Ralph] Rose's career at Michigan with that of Gregory and [Willie] Heston as illustrating the irregularities which were among the evils of football.

Gregory accepted and went to Michigan, played a dozen or more games a year, and was graduated with his class – a singular fact in connection with his failure at Stanford.

Gregory stated:"I am tired of having David Starr Jordan ... brand me as a tramp athlete.

If President Jordan will talk facts rather than trash, he will change his attitude on my standing in college, so far as Michigan is concerned.

At Michigan I never flunked during my entire course, and what the conditions were against me when I entered I made up by working hard in summer school.
