[Lord Didsbury]

I note that Burton, a team higher up the league and playing at home, made three subs. The first as early as the 55th minute.

Yet it made no difference.

The point is, that the above proves nothing. It is just one match.

But looking at stats over a longer period of time, whilst difficult to get a rock solid conclusion, still provides some reasonable evidence.

What you think you see with your own eyes is less reliable.
