To get inducted into the basketball hall of fame in Bitlife, you will need to raise your greatness bar to about 80 to 90 percent full and then retire from your basketball career before the age of 40.
Once you retire, you will be inducted into the basketball hall of fame provided you had a high enough greatness meter. Getting a high greatness meter can be achieved by practicing your skills and improving as an athlete.
Winning a few championships and MVPs will be ideal as well, but for the most part the game is very random about giving these to you. So just focus on raising the greatness meter through keeping all of your skills as high as they can be along with your fitness.
Doing should also earn you a few of both rewards, as if you are a skilled player, you are more likely to do well in games, win championships, and get MVP awards.
That being said, to raise both your fitness and skills, you will need to utilize both the practice and fitness activity options located under your job menu for the professional athlete job.
Practice will allow you to improve one skill at a sport slightly each time you do it, so it's recommended to use it at least once per year as using multiple times doesn't seem to increase it anymore after one time.
Fitness will allow you to work through three options that all target specific fitness needs, with the third being a more balanced approach to it all.
It's highly recommended to use this option alongside practice as you will need to stay fit to become the best basketball player you can be.
If you use both options regularly and keep aging until your greatness bar is at least 80 to 90, you will get automatically get inducted into the hall of fame for Basketball in about a year or so from retiring.
Winning several championships and MVP rewards on top of the greatness bar being around 80 to 90 full will also help get you inducted.
