I should add another component of Roy's fast teams was the midcourt outlet pass. Rebound or inbounds to a guard at midcourt, meanwhile a wing or two would be busting it down to the basket to try to get behind the defense...guard would bring the ball down looking for the wing behind the defense or for an open lane for a drive. If the wing was guarded and the guard drove and the rest of the defense wasn't set yet, the guard would be able to get a layup, or a short jump shot, or pass to the wing down low for a layup-dunk if the wing's defender came to stop the guard's drive. (If a defender collapsed down on the drive from, say, Boschee at the 3-point line, the pass might go out there for the open three, instead.) If there was nothing there, guard would circle back out on top and look for the trail man coming down the court as the last option in the secondary break, who might drive to the basket w/ or w/o the help of a quick screen while the defense is still getting set.
We saw Denis do a lot of that, occasionally off a midcourt pass, but more often he would just use his speed to get the ball down the court before the defense was set.
