Wrong. If my defense was good in 2k13, 2k15, and 2k16, it should be good in 2k18.
I'm not your typical defender. I don't play up close and force contact. I don't 'ram' into them several times. I give them space, watch their movements, adjust where I want them to go, cut off the baseline, etc. As I said before, all I do is play on ball defense. When you play against the Warriors and Cavs 24/7 you have no choice but to be good with on ball defense
Everything you're telling is what I've always done.
There seems to be some type of 'lag' like my player is stuck in quick sand, but the game runs fine
