This has been issue since at least 2k11 or maybe 8. Bigs rebound too well. I'm using updated Trail Blazers rosters on Allstar and its so bad that in 10 minn qtr games, with Allstar sliders against the Heat and and Timberwolves both Towns and Adebayo had 20 rebounds. This is how I need to edit rosters to make it decent.
This is to all players with both rebounding stats.
NBA
6'7 -5
6'8 -10
6'9 -15
6'10 -20
6'11 -25
7 -30
7'1 -35
7'2 -40
7'3 -45
7'4+ -50
WNBA
5'11 -5
6 -10
6'1 -15
6'2 -20
6'3 -25
6'4 -30
6'5 -35
6'6 -40
6'7 -45
6'8 -50
It works better with the WNBA and its ok with simed games. If I can make it decent with roster edits this should be an easy fix. Next gen 2k21 fixed charges/blocks and that's been broken close to deace too. The fact that its this bad means the devs don't know its a problem or don't care. This should be obvious. Its a shame because the game simulates many things well but it doesn't even come close with rebound stats and the clear obvious reason is bigs rebound almost twice as well as they do in real life. You can't just tune the sliders because its all bigs men.
I think the root of the problem is obvious . You have box out ratings, hustle ratings, hands ratings, vert and stamina with a bunch of rebounding badges and psychics advantages due to height and wingspan. This makes the rebound ratings sorta redundant. Since the rebound factor where players are on the court players are not judged based on a curve that factors opportunity. This means that players have higher rebound ratings because they tend to get more total rebounds. It doesn't necessarily mean that they are good rebounders in context but they typically have good ratings that stack with the other advantages.
One other thing that stands out is its way too easy for me to score slashing with Lilllard than shooting. Dunks should be much harder to come by and threes should be easier.
This is concerning too after reading this gameplay quote.
Bigs are already too slow. Giannis and Brianna Stewart are problems because they outpace bigs not guards. They outpace bigs because bigs are generally too slow so the athletes who can handle the ball are ridiculous slashers in transition when guarded by 2k's slow tall players. NBA 2k generally needs more speed parity not less. Its already much too easy to score in transition with guards.
