Shrewsbury boss Graham Turner had no complaints about the penalty that decided the 1-0 defeat at Doncaster.
But Turner felt his side should have had something to show for all their hard work.
Rovers snatched the lead in the third minute when Billy Paynter converted the spot-kick after visiting skipper Matt Richards had brought down David Cotterill. But the home side failed to build on their lead and were fortunate to hang on at the finish as Shrewsbury squandered a number of scoring chances.
Turner said "I didn't really see the penalty incident but when a player goes to ground it makes it difficult for the referee not to give the award.
"I just thought we lacked a bit of sharpness in front of goal because there is no doubt we deserve something from the game on effort alone.
"We've come away to a team that was in the Championship last year and shown a lot of character and hard work. It was a poor goal to concede but I don't think our keeper had to make a save after that.
"We had chances to equalise and I thought we definitely deserved a point but we just weren't bright enough in front of goal. That's the way it's been going for us this season. We've done ourselves proud with the way we've played and won a few friends but not got the points our performances have merited."
Doncaster looked set to go to record a convincing victory after their early breakthrough. But although they produced some good football in the first half they lacked an end product and hardly tested visiting keeper Chris Weale again.
Rovers' boss Dean Saunders said: "Some of the football we played in the first half was brilliant and we should have really finished them off there and then.
"But we couldn't get the final pass right at times and missed a couple of good scoring opportunities. The second half was a complete contrast and I'm just pleased to have the points in the bag."
