While the Astrodome ameliorated the hot, humid climate, it had several drawbacks as a venue for the Oilers. Despite being almost completely round, the Astrodome's football sight lines left much to be desired. The seats near the 50-yard line, usually the most desirable (and expensive), were the farthest from the field of play, while those nearest the action were otherwise-undesirable seats in the end zone. Additionally, the Astrodome seated only about 50,000 for football, just barely over the minimum seating capacity for an NFL stadium. By the early 1980s, it was the smallest venue in the NFL. Adams chafed at being the Astrodome's "secondary" tenant. He knew his position was unlikely to change as long as the Astros were playing 81 home games and his team was playing eight.
