In 1972, the Lions improved to 8–5–1. In the following season, they regressed to 6–7–1. Heart disease claimed another member of the franchise when head coach Don McCafferty died shortly before training camp in 1974. That season saw the Lions finish at 7–7. On Thanksgiving Day, November 28, 1974, after over 35 years, the Lions played their final game at Tiger Stadium, where they lost to the Denver Broncos 31–27 in front of 51,157, amidst snow flurries and a 21–point Broncos third quarter. The Lions moved to a newly constructed stadium in suburban Pontiac. Another 7–7 record was produced in 1975, the Lions' first year indoors. This was followed by a 6–8 showing in 1976. The team finished with an identical 6–8 record in 1977, struggling the whole season with an anemic offense that only put up 183 points. More mediocrity followed in 1978 with seven wins in the newly expanded 16-game season. The bottom fell out in 1979 with a 2–14 record.
