Playing careerEdit

College footballEdit

Flenniken played college football for Centenary College of Louisiana in Shreveport and then at Geneva College in 1926 and 1927.[2] His college career mirrored Cal Hubbard who played for both colleges and also later became a coach at Geneva. Both players followed Bo McMillin, who coached first at Centenary and then later at Geneva.

Chicago CardinalsEdit

Flenniken got his start in the NFL with the Chicago Cardinals in 1930.[3] He was a flexible player on both sides of the ball, recording three rushing touchdowns and also showing a threat using the forward pass and picked up an interception while playing defense.[4] At Chicago, he played alongside future Pro Football Hall of Famer Ernie Nevers.[5]

New York GiantsEdit

In 1931, Flenniken moved to the New York Giants,[6] where he was a part of the "committee of quarterbacks" along with Red Smith and Hap Moran.[7] For the Giants, Flenniken saw less playing time but in his four games and one start[8] he recorded successes in both passing and rushing.[9]

Coaching careerEdit

Flenniken was the 14th head football coach at Geneva College in Beaver Falls, Pennsylvania and he held that position for two seasons, from 1928 until 1929. His coaching record at Geneva was 7–11–1.[10]
