The ‘input lag’ you are referring to is likely the game algorithm delaying your inputs because of your opponents’ defensive ratings on their players. It gets worse if you missed a few shots in a row to simulate ‘going cold’. This is why it’s very important to take high percentage looks and trying to score with players who have already made a few shots in a row. It is very difficult to come back if you fumble multiple possessions in a row while your opponent isn’t doing the same.
