Andy Scott says Bristol Rovers came for a point and got three as the visitors ended Rotherham's four-match unbeaten run with a 1-0 win.
On-loan Andy Dorman scored his first-ever goal for Rovers, firing home from substitute Eliot Richards' cross in the second minute of time added on.
Scott said: "If you don't do enough to win the game, you always leave yourself open to lose it. I suppose that's the worst way to lose it, smash and grab, whatever you want to call it, but they came for a point and got three.
"I don't think we really deserved to win the game but neither did they. We had a couple of good chances early in the second half, Lewis Grabban probably had the best one and Alex Revell had a good one but it's the same old story.
"It's a lack of quality and being too anxious to score a goal as soon as we win the ball back. It was a poor game, especially first half when we cancelled each other out. In the second half we came out with more intent and we created chances, but again we left it to the second half to do that.
"Then we gave the ball away in a poor area and lost a goal right at the end, but there was no sustained pressure and our pattern of play wasn't what it has been over the last four games."
