Mick Adams was relieved to snatch a point from Sheffield United's trip to Coventry City in the Championship.
The Sky Blues dominated mustering 17 corners and 21 attempts on goal compared to the Blades' six and four.
However, they failed to find a way past United goalkeeper Steve Simonsen who denied them on several occasions - while Gary McSheffrey hit the bar twice with free-kicks and blazed over a late chance.
Blades boss Adams admitted his side had good fortune but was delighted with the overall defensive display.
Adams said: "We rode our luck at times but in terms of defending when we had to we were excellent, particularly from corners and free-kicks and especially in the first half.
"In the second half I thought we came into the game a little bit and probably had the best chance of the game to nick it - and it would have been nicking it to be fair.
"I was delighted Steve Simonsen kept a clean sheet because it is demoralising for a keeper to keep seeing the ball in the back of the net."
