I'm not sure we even go after a darby type if we keep running Schwartz D. Schwartz was a ton of zone, with backers filling in those gaps in the running game. Leodis is actually a pretty good zone corner - while darby seems to prefer man coverage.
Also, if people played this crappy in Schwartz scheme, we'd look even worse. We'd give up like 200 yards rushing per game if we tackled this poorly in a wide 9.
