Sherri Coale (see video below) emphasizes entry passes ABOVE the SHOULDERS or BELOW the WAIST. Defenders are all over the middle passes.
Nuances of getting open in the post are not included.
The point guard relocates to below the foul line to improve passing angle.
Against the hard front, the offense can SEAL the defender with quick ball movement, locking x5 behind 5. SEAL on SWING.
The best guards get the post the ball in the best position. Kevin Eastman differentiates post residences. 1 is the "homeowner", 2 a "renter", and 3 is homeless. Both post and passer need 'realtor' mentality - location, location, location.
Aggressive guards will "dig" or "double" the post. Smart passers remove that possibility through pass and cut options.
Post entry starts the first option in the triangle offense. Expect to see less triangle as Phil Jackson and the Knicks have parted ways.
Passing quickly THROUGH the post can set up easy baskets.
Classic "blind pig" for a wing back cut. A second approach involves the 5 dribbling away, then pivoting (wheeling) to deliver the pass.
The Celtics like to run a corner blind big action with Avery Bradley at the 2.
This horns action through the high post give-and-go is elegant. Can't remember where I saw it.
The US Women's National Team (USWNT) ran post entry into combination actions, looking at flare screen 3s or dives to the hoop off the slip (above).
If we have skilled post players, we want consistent post entry. If they're less proficient scorers, then we need to teach them to find teammates on passes through the post. In either event, we need to show them how...Coach Wooden's explanation, demonstration, imitation, and repetition.
