You get the same effect by passing the ball into the post and then, if the post is doubled, kicking the ball out to the open shooter. Or by throwing the ball to the high post, who looks to find a cutter to the hoop, and if the cutter draws a defensive rotation, the high post player can kick it to the open shooter. Or the high post player can hand off the ball to a shooter who can take advantage of a ready-made screen.
All of these alternatives are speedier than putting the ball on the floor. So UConn guards typically don't drive to the basket unless they can see an open path to get all the way there. Otherwise, one of the above alternatives is preferred.
Having seen small guards like Ketia Swanier and Lorin Dixon drive into the paint, get surrounded by trees, and then say to themselves, "OK, now what do I do?", I think Geno decided that the alternatives are better. If nothing else, they put the passing decision in the hands of a post player who should have a better field of vision to see open shooters.
