Listened to an old podcast (2018) with the writer of Tin Cup - Ron Shelton. Some great insights. This guy also wrote Bull Durham, White Men Can't Jump, etc.
He always wanted to write a golf movie, but needed a hook. Chip Beck laying up at the '93 Masters gave him the idea - write a story about a guy that cannot lay up. The idea that what makes someone great can also be his downfall.
Also, they were failing at getting any PGA Pros involved; then they turned to McCord. Instead of calling the agents, McCord called the player's wives. ''We will cover the costs and you will get dinner with Kevin Costner". Suddenly they had PGA Pros involved. 😁
