Grayson's 1932 freshman team also included Bob Reynolds, Monk Moscrip and Bones Hamilton, and came to be known as the "Vow Boys". The 1932 Stanford varsity team was soundly defeated by the USC Trojans (USC). After watching the defeat, the freshmen players got together and vowed that they would never lose to the Trojans. In November 1933, Stanford defeated USC, and Grayson scored the Indians only touchdown. "Time" magazine reported that "Stanford's speedy Fullback Bobby Grayson slashed and passed through the Trojan line, punched over a touchdown", resulting in a "resounding crash" for "the fattest Humpty Dumpty of 1933 football." The Stanford team proceeded to beat USC three straight years from 1933 to 1935 – making good on the vow. Stanford was the dominant team on the Pacific Coast, appearing in the New Year's Day Rose Bowl game in each of those three years. In three seasons, Grayson was part of a Stanford team that compiled a 25–4–2 record and became the first team to play in three consecutive Rose Bowls.
