Well, while it is highly desirable, beating Torquay might not be as essential as it currently seems.
If you work from Halifax backwards, Halifax need a better result than Solihull to finish in the top 3. That means they are going to have to go for it at EP. Can't simply shut up shop for 90 mins. Even if we beat Torquay, we can't play for a draw v Halifax because we'd almost certainly lose and its not Dave's way anyway.
So the Torquay game, what we mustn't do is lose. But a draw isn't a complete disaster.
