Sometimes, when a coaching staff draws up a play in a meeting and brings it to the team on the court, it translates well in practice but doesn’t work in a game situation. They’ll run it a few times against different opposition with different personnel, but after a few tries, it’s usually pretty obvious if things aren’t going according to plan: either players forget their part, the defense doesn’t react like it’s supposed to, or any myriad of other reasons why coaches would stop using a particular set.
For the Hawks, they experimented with a set play I call “Horns Split Step” against both Indiana and Utah…and then haven’t run it in the six games since the win over the Jazz on March 20th.
