From former coach and ESPN announcer Fran Fraschilla:
Here are some things that are important for post players:
1. Always catch the ball and look to the middle.
*By doing this, a post man can see 90 percent of the court. He can locate his defender, see where double-teams in the defense are coming from and locate his teammates cutting to the basket.
2. A post player should always initiate contact in the lane.
* You can 'read your defender and which way to make a move when you get your body on him and know where he is. For example, when you "seal" your man away from the basket, it creates room to set up the lob pass over the top.
3. A post player should have a favorite move and a counter move.
* It is usually a waste of time to teach a player five or six moves inside because they wind up using none of them. It is better to perfect a jump hook or turnaround jumper. And, like a pitch who has a change-up to go with his fastball, a counter move is needed. I like the "up and under" where you fake the jump hook to get the defender off his feet, then step through and power the ball through the basket.
4. When rebounding, always keep your head and hands up and move towards the basket
*Rebounding is mostly about effort and desire so go hard to the basket on each shot.
5. A good rebounder anticipates where the missed shot will go.
