Played a couple quick games, before jumping into MyCareer. Currently about 18 games into the season, played them all, yea I took most of the day off.

Haven't noticed much improvement spacing wise. Still seems to get cramped and clogged up at times.

Collisions are much less magnetic. The suction is gone, and in its place friction is added which is the way it should be. You'll still get slowed down manoeuvring through the paint, which is a good thing.

Blocks actually happen. Don't seem OP yet.

Pick and roll rotations improvements are noticeable immediately. Much less dish to roller for easy bucket cheese. As a big man defender, I just got rapped by not hedging around the screen to put pressure on Steph Curry. Exactly as it should be.

Disappointed by the ball movement and offense setup. Haven't seen teams take advantage of big men like I read in some previews.

Biggest UGHHHHH for me thus far is that shot selection is whack. Jeremy Lamb took nearly 40 shots last game while Durant had taken 2 (no joke) up until the last 2 minutes of the game (then he scored 8 quickly which was nice to see). Next game (currently playing) Lamb already has 7 shots in first 5 minutes.... ugh....

3 pointers in general just seem WAYYYYYY too frequent. San Antonio was 16-34 from 3 last game. Penetration seems to be severely lacking, as well as midrange shots. It's all inside from a dish, or long range thus far. Supremely disappointed.

Minor improvements to MyCareer are nice to see. The drills menu restructure, the increase in skill points given after each game, also as a player you seem to progress faster. I'm already starting for the THunder after maybe 15 games, even though I'm only 68 OVR, although I've been putting up double doubles over the last 5 games.
Controls are iffy. Seems to be new dribble moves, which look nice for certain players, but simple things like pump fakes, are difficult to make now. And in my little experience, I did shoot a few unintended shots.

When playing 5v5 (ie outside of MyCareer) I have a problem with the control and camera relative setting. So you can set the right stick to be camera relative or absolute as last year. I like dribbling with absolute but shooting is just much more intuitive with camera relative. I know the easiest remedy is just to get used to camera relative, but it would have been nice to differentiate the camera relative/absolute setting for shooting and dribble moves. This coincides with complaints users have with the right stick being too busy. Honestly I haven't fiddled too much as I'm a big man and have really only used it for post moves thus far.

Rebounding still sucks. Come... on...

Weird possessions where CPU players hold the ball and do nothing for the full shotclock are still there. Maybe once a game (so pretty often, more than I remember).

Contact and shots inside are much improved.

Late game CPU AI seems improved, teams will begin throwin 3's when down big with time running out.

I had the game set on Arcade mode for ~8 games by accident, and noticed too many 3's. Switched to simluation, noticed zero difference in
anything honestly. If anything maybe even more 3's. No difference in pace, passing, low post action etc.

Pace is the way it should be. For the first time in a year I've finally seen teams have greater time of possession than me. Fast break bug (and it was a bug) is gone. CPU will break out when appropriate without stopping and hucking a midrange shot just because you didn't convert on the other end.

Ball seems to be more open to physics ala 2k12. More loose balls from dribbling, more strips and turnovers etc.

Loose balls still seem to be far in favour of the CPU. Blocked shots always wind up back in their hands. They get offensive rebounds off of close misses because they recover faster from a shot, than you do from a shot-contest. Hustle slider may fix this however.
Summary
Many noticeable improvements, much better overall feel, however shot selection is frustrating right now. Shouldn't be an issue outside of MyCareer really though.
I rate it FIVE BBQ ribs out of THREEVE chicken pot pies.

Side note question (in the wrong place). Anyway to adjust MyCareer sliders (ie tool) without having to start a separate program every time before starting up the game
