Resources for attribute systems in a sport sim

I'm working on a golf sim as a hobby project and I'm currently working on the player attribute system which will probably be one of the most critical mechanics in my game. While I have a set of attributes already in mind/implemented I'm specifically wondering about calibration methods and progression mechanics so that scores in the game develop in a realistic and consistent way across the whole player population.

The main resources I found so far are the Basketball GM repository and blog as well as some blogposts on the game design of baseball mogul (https://thegamedesigner.blogspot.com/).

I would appreciate any pointers on good resources or also all other kind of input.

Thanks
