Surely it falls on the manager either way? Either we are training this way and putting in to practice in matches or we are training to play another way and then it goes out the window on match days. Regardless, the manager should be making sure that doesn't happen. Given how reasonable a reputation Jim has for being a decent "man manager" then I'd be surprised if it is the latter.
I do, however, agree that we have players capable of better and I also that feel we are 1 creative midfield player away from being a much better looking team to watch. Touched on it a couple of days ago, but I feel a fit Crossan, Wilson and Frizzell with 1 other would be a decent attacking force from the wings and strikers. The issue for me at the moment is that I haven't seen enough from Johnstone or Jones to suggest they are up to being the 4th player on that set up. Even though, on paper, they should fit well with being a target with those players around them.
