Generally I agree.Wiscy's hedge man is below ball-level, hence "drop" coverage.
A guy would get hot from 3 vs Dr. Tom's zone, or after breaking the press, and Davis wouldn't really adjust. Little different game back then and he would kind of live and die with his style of D. And some open 3's were a weakness of his defenses.
Teams get hot vs Fran because Iowa is playing overall bad defense. They don't contain the ball, which leads to premium looks for shooters after the defense has been broken down. Teams come into a game feeling confident that they will get good looks against Iowa. Playing against Iowa's defense is literally a breath of fresh air after getting pounded on and suffocated all season long in the Big Ten. Teams feel like it's their birthday. Sometimes a few weeks worth of a struggling grind on offense all gets taken out on Iowa.
It isn't that teams get lucky over and over against Iowa. It's more that teams feel that it's their God-given right to score against Iowa. There is no curse from the bball gods. It is the curse of a failure to prepare
You can almost see opponents eyes light up when they find themselves isolated on the perimeter against Patrick or Payton.
