In 1924, Behman joined the Frankford Yellow Jackets, a long-established team but then new to the NFL. He emerged as a placekicker in 1925, hitting on five field goals and twelve PAT's. In 1926, he jumped to the new American Football League's Philadelphia Quakers, but when that league folded after one season, he returned to Frankford. He was twice named a first-team All-Pro. In 1929, he assumed the role of player-coach, still playing the line on both offense and defense and dropping back to punt. The following year, as the team began to run into financial problems, Behman resigned. His career NFL coaching record was 13–20–7.
