If you've seen any inside bigs that know how to play the post this year, it's pretty obvious that post control and close shot are way more effective than last year.
Drop steps, post spins/drives, up and unders and fades are all pretty strong and basically uncontestable if you get a mismatch. Coupled with the fact that post control and close shot are a lot cheaper for bigs in the builder this year and shooting is harder overall, you have a way better environment for inside bigs to play their game.
Personally, I've been having a lot of fun working the post on my big. Trying to figure out what combination of moves works best for a given situation, hitting the open man if I draw a double or get a bad animation and learning how to guard the post effectively myself.
I really hope 2k doesn't nerf post play again this year. Post moves definitely feel strong right now but I just don't think the player base is used to countering it yet. A lot of bigs don't know how to guard post moves and it shows.
If you want to underinvest in interior D or strength as a big, or jump at everything, that's fine but your team is going to either need to send a double, or get cooked.
