yea that's why it's lame. Dudes can just turn and dunk on you, but as a post scorer you have the ball longer, so it's more live. I remember when I was younger playing ball, getting yelled at by older players for trying to dig in and swipe at a post player as the player i defended curled off them. It's true, it's really not a good basketball play, yet as soon as you get the ball in the post in 2k, everyone swarms around you mashing square. You get the ball off a rebound, same issue.
I said this before, and I think there should be a contact/engage animation when you dig if you want to actually pressure the ball. Makes it so you can pressure a defender but it's not always a steal and it's not like hot potato in there. I am good at passing, but it's cuz I know someone could take the ball from me at any time.
Another issue is the 'strength' of the side of your player. You get a back down animation if you back into someone, but in truth, your side while posting should also be strong. People shouldn't be able to just swipe through you from the side or disengage and walk around you to try for an easier steal.
I think it's hard to steal the ball in 'real life' from post players. They can all palm the ball really well, they are probably strong, they subtly turn their body, etc.
Think of how many times you see someone take the ball from LeBron while he's dribbling. He's a strong, talented dribbler who doesn't make too many mistakes, but he still gets ripped. Then think of how many times you have see him getting ripped in the post. Then think of some pretty mediocre dribblers who are post players, they don't get ripped. It's generally a bad play to swarm the post; playmakers can dribble back and forth in your face, but if you are posted up, you have to worry about people flying through with lunge steals and knocking the ball loose.
Stealing from high str post scorer primary players should be either blind side or should go forced pick up into double or strip.
