2K has done a good job with Michael Jordan since 2K11. But as a Jordan fan, I feel that some tweaks are needed to fully emulate His Airness.
And if you think there are more changes needed, feel free to suggest.
Jumpers : For 93-98 Jordan, the M.Jordan form and base are perfect. But his shooting form changed through the years. He used to jump higher and hang longer in the early days. So change the base to Jumpshot 24 for 86,89 and 91. He also used to hold the ball to his right side (based on his 82 NCAA game winner). I'm using R.Gay for now for 86 MJ.
Runner : Give the Jordan runner to 91 MJ! He did the move in the 91 finals. I don't know why 2K keeps giving it to 89 MJ.
Dunks : I don't know how the dunkpacks work. But I always remember him leaning in and jam almost every breakaway so I give Leaning Slams as his go-to dunks (aside from 86 (Historic Jordan, as I want him to do the cradle dunk as often as possible, haha) and 98(basic one-hander off one)). Add Leaning Windmill for 86 and 89 for his 'Kiss the Rim' dunk. He used to do that in game once in a while.
Dribble Moves : MJ isn't known for flashy handles. Crossover 3 and 4 seem like what he would do the most to me. Spin 5 is fine. Behind the back 5 or 7. Hesitation 1 or 2.
And last but not least, M.Jordan Powder2 pre-tipoff ritual for 89-98. I don't know when did he start to do the powder clap, but I think it's late 80's.
Enjoy being like Mike!
