The zone defense wasn't just invented but it was the first time for KJ to deal with something like that. The issue wasn''t that Leach hadn't seen it before, the issue was KJ hadn't seen it or had to make decisions against it in real time before. Its one thing to tell someone how to operate against that defense but a whole other thing to actually do it. Decision making is apparently a whole lot easier with this offense when everything is man. Folks still forget just how little time Leach has had to get this team ready to run this scheme and run it against various defensive looks.
