Football also wasn't quite as popular, so while they could move in temp seating, it wasn't always needed. Last team I saw with a dual use stadium was Oakland.. and maybe it still is? Candlestick park still looks more like a baseball stadium than football to me, even without the diamond.

Football field size: Football games are played on a rectangular field that measures 120 yards (109.7 meters) long and 53.3 yards (160 ft (49 m)) wide.
