I remember the article in Sports Illustrated entitled "How to Turn up the Heat" and it was a short article with a huge stick figure diagram on the Iowa full court press. Guy with biggest arm reach guarding the inbound pass... 3 dudes playing Defensive Back, and your best shot blocker in the lane.
The pass around the long armed fella (Lohaus) would get picked off by either (Marble, Armstrong, Gamble, Moe, etc.) and someone like Horton would be at the back end playing as the last line of defense. When the ball was picked off, they would just attack the wings with the long armed fella already under the hoop.
Those were the days... remember the Illinois game when Iowa was getting beat badly and Davis came out in the second half with a full court press and Lohaus went OFF!!!? That was one of my favorite games of all.
