Please teach me more about Bud Adams saga

1. When both Oilers and Astros owner said "I want a new stadium", only Astros got what they want. What's the difference?

2. If both of Astros and Oilers got a new stadium, what would happen to the economy of the city?

3. What are some classic examples of how Bud Adams make Houston citizens and politicians feel mad?

(Actually I posted the same question at r/NFLv2, but the comments were less than I expected. So I decided to write the same thing in here to get more information)
