The 1921 season was Bryan's only full season of cricket as his job as a teacher prevented him playing regularly outside of the school holidays thereafter. He scored 1,858 runs at an average of 50.21 including five centuries, three for Cambridge and two for Kent. His highest score of 231 was made for Cambridge against Surrey at The Oval and in a series of eight matches he scored over 1,000 of his runs. He was awarded the accolade of being named as one of Wisden's five Cricketers of the Year in the 1922 edition.
