This might bring some randomness to a progressive
Ex. Its the 71-72 nba draft and you select Julius erving, he plays for the Virginia squires for 2 years before becoming a disgruntled player on your team. You must choose to either trade him, release him or have a disgruntled player sitting on the bench receiving no minutes
The next gm/coach will roster him for the next 3 seasons before he wants out and the next owner must roster him the rest of his remaining seasons with the 76ers
Draft a player like kobe bryant and you must roster him and cannot trade him his whole 19 year career
