Could be down to several factors Joe, as you hint. The pitch was certainly one.
I think Falkirk are a better all round team than us and have the playing squad to mix things up and vary tactics. We, on the other hand are a better pure footballing side, if that makes sense.
We have deficiencies in the squad which have come to the fore of late. For example, no cover for left back and a lack of strikers. I know Thor is still is still realtively untested and injured to boot. With quite a few players leaving in the summer Nicholson, Halliday, Gordon etc. it will allow us to address outstanding lacunas.
