As a junior, Harrigan and Bennie Oosterbaan led the 1926–27 team to a 14–2 record and the school's first outright Big Ten basketball championship.

[5] A December 1928 newspaper article on the Cook team noted: "Frank Harrigan, one of the regular forwards, was an all-Big Ten selection during his three years with the University of Michigan.

Harrigan stands two and a half inches over the six-foot mark and is one of the fastest men on the squad.

"[6] Harrigan was known as "a deadly shot" for the 1929 Cook team,[7] and was selected as a first-team AAU All-American for the 1928–29 season.

From 1931 to 1934, as elite corporate AAU teams began to evolve toward the creation of the first professional basketball league,[8] Harrigan played for the Akron Goodyears.
