if you are playing against a weak inside defense, slowing down the offense will decrease your field goal percentage because of the last second shots..
if you think that you will be able to score %30-35 of the inside shots you will try, go for Low Post so it can take your field goal percentage up to %40-45..
you also have to be careful about passing and handling when playing Low Post because as you keep the offense longer, the possibility of a turnover will increase..
Are you guys saying that the shot clock is a factor of ur shot accuracy?
