Pressure, and train it until you get to about a 9 or 10 (at minimum, I might go up to at least 12 before I moved my focus onto another skill). At 6'7, OD takes a little longer to train and it is painful when you are trying to train OD at 23 or 24 years old and it takes 4 weeks to pop. If you want to break it up a bit, throw in a JR or One-On-One forwards.
And as far as the slowest skill to train, it depends on the player's height. Generally speaking, OD trains a bit slower than most skills, but it is also one of the best. However it will train faster than post skills for a player who is 6'0. Passing and Ball Handling train quite fast, regardless of height.
