Hmm...havent played in a few months but....lemme see. When you want to do a pullup, let go of the left analog RIGHT BEFORE you shoot. And hold it down for a sec. It sounds like ur trying to pull up in front of someone and you you are tryna release hella fast so you don't get contested. As far as the latter, I think everybody does that here and there. Its gonna happen to you sometimes regardless. Its just some 2k shyt. But what I would do is just hold turbo (or not if u tryna layup, float it etc.) But when you get close enough, DONT let go of the left analog! And instead of pulling back on the shot stick, try holding both analogs toward the basket. Try it out and lemme know if you made some progress
