You know, I dislike the Gophers as much as anyone, but I think you might be reading a little more into the "development" comment than is really there. How about if the Wild just decided they don't like the way Leddy himself has developed, without comment about the program. You know, like they thought he looked really good as a high school senior, but now that he's nearly a year out, they're thinking maybe the kid hasn't grown physically or emotionally enough to justify their continued interest.
I'm sure there are a lot of former Sioux players whose development didn't live up to the expectations of the teams they were drafted by. Several come to mind in just the last three or four years. See if you can come up with a list of your own.
