I try not to get too despondent when results and performances are poor, although it's been especially tough recently. By the same token, I don't let myself get carried away after one good performance, but at least we can look forward to the next game with a degree of optimism.
PG will not necessarily be sacked if we lose, but it would heap some more pressure on him. If we really have turned a corner and go on a good unbeaten run, calls for his head will disappear.
