I agree, both games need a bit of tuning in that regard, from opposite ends of the scale. Sliders can help - sometimes - but beyond any problems with slider effectiveness, it's a moot point in modes where you can't adjust sliders at all, such as each game's team building, pro-am, and single player career modes.
As it happened, I played a full Tip Off game of NBA Live 16 yesterday, to get a few screenshots for an article. At this point, the game feels a lot better than it did at launch, and I can still see a lot of potential in it. There's a ways to go, but I hope that the extra development time for NBA Live 17 does pay off, and that the console platform isn't abandoned as has been speculated.
