Runs that don't work mean fans want a pass. Passes that don't work fans want runs. Have you noticed that neither works that consistently well. You have to run and pass. When a play doesn't work it doesn't mean the play call is bad. Thats my number one beef about football fans. It sounds so pee wee.
I think Corny has demonstrated he knows how to call plays. We don't put up 58 pts a game because we aren't that talented. You can certainly debate whether our overall O scheme is a winning formula which it was not in the Beamer era. But don't just say every play that doesn't work is a bad call
