He testified in a 1957 drunk driving case against former teammate Bobby Layne that he had served Layne six or seven scotch and waters, but nevertheless believed that Layne "was very capable of driving." Layne was found not guilty. Bingaman also testified that the Scotch he served had "practically no alcoholic proof," prompting one Detroit columnist to write, "Greater love hath no man than he should ruin his business for a friend." In 1959, he sold his bar, and in 1960 he was hired as an assistant coach by the Detroit Lions. He replaced Buster Ramsey as the Lions' defensive line coach under head coach George Wilson. He served for five years as the Lions' defensive line coach, leading a group that became known as the Fearsome Foursome (Roger Brown, Alex Karras, Darris McCord, and Sam Williams) and was acknowledged as one of the best defensive lines in the NFL. After the Lions compiled a 7–5–2 record in 1964, team owner William Clay Ford, Sr. fired five assistant coaches, including Bingaman. In February 1966, after spending 1965 working as an NFL scout, Bingaman was hired as an assistant coach by the Miami Dolphins. He rejoined his former boss, George Wilson, who took over as the Dolphins' head coach one week earlier. In January 1967, Bingaman rejected an offer from Joe Schmidt to return to the Lions, opting remain with George Wilson in Miami. On December 7, 1969, he collapsed on the sidelines during a game against the Denver Broncos. He had no pulse or heartbeat for three minutes and had to be revived with a shot of adrenaline injected into his heart. He was diagnosed as having suffered "an irregularity of the heart-beat which caused him to go into temporary shock." After the 1969 season, George Wilson was fired by the Dolphins and replaced by Don Shula. In February 1970, Shula offered Bingaman "a position involving special assignments." He spent the year as a special assistant, scouting college players for the Dolphins. Family and death Bingaman was married in 1949 and divorced in 1956. His wife alleged in the 1956 divorce proceedings that Bingaman "beat her, neglected her and made her feel unwanted." He later remarried, and he and his second wife, Betty, had a son, Lester Bingaman III. Bingaman suffered from weight
