The Astrodome, built in the mid 1960s was the first major indoor stadium for baseball and football. One of the unique features was a unique "exploding' scoreboard that flashed all sorts of fancy (for its day) graphics and stuff whenever the home team scored big (touchdowns, home runs, etc.) It covered the top three levels of the baseball outfield and football end zone.
In 1987, Adams, seeking more revenue, visited Jacksonville, Fla., several times and toured the Gator Bowl and made a very public noise about moving the team. Harris County, which managed the dome, got scared and tore out the great scoreboard and added seats in those top three tiers to encircle the entire stadium and increase the football seating capacity from around 50,000 to about 65,000. This obviously provided more revenue for football, but the seats were rarely used for other events.
Less than a decade later, Adams was back whining to the county leaders about needing a new stadium and bolting the Astrodome altogether. When county leaders balked this time, Adams moved the Oilers to Nashville.
My feeling is if Adams had been a little more quiet and politically-savvy about things, he would have gotten the new stadium (which was eventually built for the Houston Texans) anyway. But by making such a public issue of the whole thing, he put the elected officials in a tough spot. If they went along with him, they were seen as giving in to the blackmail of an owner who wasn't real popular to begin with. So they called his bluff and he left. The Texans came just six years later and it turned out everyone was better off.
