1. The drill begins with live four on four action taking place at a basket. On the shot by the offense or the command of "change" by a coach, a conversion takes place. If a shot is taken two forwards or bigs attack the offensive glass while the two guards get back on the shot. A coach is assigned the offensive rebounders and a second coach is assigned the two guards "getting back."
2. On the conversion, all four defenders must cross the halfcourt line in 2.5 seconds or the drill stops and the four converting defenders will run. As the drill continues the defense gets set and live four on four action takes place at the other end. Once again, on a shot by the offense or the command of "change" by a coach, a conversion takes place. There is no out of bounds. This action takes place for several minutes. The coaches are paying particular attention to offensive rebounding, getting the guards back on the shot and making sure all four defenders cross halfcourt in 2.5 seconds or less.
3. To ensure more shot attempts the shotclock can be shortened for the offense promoting more rebounding opportunities and more conversions.
