Yes, that's right, box-out on offense. Other offensive skills to look for, even though they may not be found, are dribbling the ball from the top, not the sides, with the wrist and not the arm, and a high free-throw shooting percentage. On defense look for players in defensive position, ready to run, with the knees bent, not the backs, weight on the toes, and feet at slightly greater than shoulder width. Players jump-step to keep up with the offense. Jump-steps are short jumps to keep up with the defense, rather than sliding and crossing the feet like we see with football linebackers.
All defensive eyes are on the ball, so players can readily help out.
When the ball is shot players box-out and all players, including the guards, go under for rebounds. These are some skills readily noticed on a well coached team. Know that the best coached team will not always win the game or the championship. Winning teams are teams that are physically superior to the opponents. Winning coaches recruit these superior athletes and need them to win.
