Within four minutes of beginning the process of mass changes that disrupt virtually every modern-day rugby match, Worcester conceded their first try against London Welsh.
They went on to ship four in the space of 21 minutes as a Warriors machine that had functioned so smoothly for the preceding hour, spluttered and virtually ground to a halt.
The week before it took around ten minutes before the wheels started to come off and Nottingham sliced their way to three tries at a time when they should have been out on their feet.
It is the Worcester approach to lumberjacking. Pull up the trees but don’t clear them and then bemoan the fact they have taken root once again. It is also the seed that gives their play-off opponents hope and the one that makes Warriors’ promotion anything but a sinecure.
However, despite what the statistics say Tom Arscott denies that the habit of making wholesale changes early in the second half is the reason for his team’s tendency to take their collective foot off the gas.
The full back played the whole 80 minutes in both matches and believes the culpability lies not with the men who come on, but those who are there already.
“I don’t think making replacements matters at all,” the 23-year-old insisted. “We have got such strength on the bench and through the whole squad that bringing boys off the bench is strengthening us rather than weakening us.
“I think it’s just us switching off, maybe the boys starting aren’t doing a good enough job for the boys coming off the bench and it looks like it’s not helping us – but it is definitely not the boys coming off the bench.
“Against Welsh I don’t know if we switched off a little bit when we almost had the game won. We played very well for the first 40, then we came out after half time and the start of the second half wasn’t too bad – we got in their half then there was a turnover which was the turning point.
“They got on the front foot, started throwing the ball around and we didn’t deal with it particularly well. I think being 32-3 up at half time mentally we were not quite on it.
“We need to start playing for the full 80 minutes. At Nottingham we got a good score up then started letting them back in the last 20 and it was the same story against London Welsh. Hopefully we will work on that in the next few weeks and come the play-offs we will be working for the full 80 and not just 60.”
If Worcester do that, then they are almost certain to swat aside their rivals – but if they don’t there could be trouble.
