The sideline play when the game needs a post score with eight to twelve seconds: Hoop Coach's post isolation from the box and Coach's Clipboard's half-court "Chicago" buzzer beater. From the sideline box the two elbows down-screen, the handler pops to the wing for the entry and the ball swings to the top; as it swings, the weak block sets a diagonal cross-screen for the best post, who seals on the ball-side block. The screener finishes his cut at the ball-side elbow, and a shooter standing there keeps the elbow defender home, so the post catches one-on-one. Why swing before the entry: a post entry from the sideline is contested from the baseline, and one from the wing after a swing arrives with the help on the other side. The read is the post defender: fighting over the cross screen means seal high, going under means seal low. The counter is for the defense that switches the cross screen or doubles the post on the catch: the post reads the double and kicks to the screener at the elbow, Coach's Clipboard's two-man game, for the elbow jumper or the re-entry. Common mistakes: the entry thrown before the seal is set, the screener leaving the elbow so the help has a free run, and the post putting the ball on the floor against the double. The post isolation is Hoop Coach's and the two-man game counter is Coach's Clipboard's half-court Chicago; I learned the swing-then-enter idea from both, and give them a look.
