Rival bosses Mark Robins and Gary Bowyer both thought their side should have edged this Ewood Park stalemate.
But Huddersfield Town chief Robins still rated it a “great point”, explaining: “We could have nicked it, so could they.
“In my view, we were the side more likely to do something, but the draw was probably fair.
“We’ve come away from home, kept a clean sheet and taken a point. Last season we came here and lost 1-0.”
Robins reshuffled, both before the game and during it.
Swansea loanee Jazz Richards was handed a full debut at right wing-back, with Adam Hammill pushed up behind strikers James Vaughan and Jon Stead.
“It wasn’t the best of games, a little bit dour, but we managed to grow into it a bit,” he said.
“In the first half, we were on the backfoot at times, but that was as much down to us as them.
“They didn’t create too many clear-cut chances, and when they got crosses in, we dealt with them quite well, if not the centre-halves, then Alex (Smithies).
“Our distribution was okay, but we didn’t have enough movement in the middle of the park so then it went a little bit longer and we left James Vaughan a little bit isolated.
“We need to work a bit harder without the ball and work a bit harder to retain possession high up the pitch.”
Robins made his first change six minutes into the second half.
Midfielder Oscar Gobern replaced striker Stead, and the boss added: “Oscar helped us clamp down on Tom Cairney, who had caused us some problems in the first half.
“They then went deeper by 10 yards and that stopped them pressing as well as previously.
“Things began to liven up for us a bit, and we got into some good situations.
“Paul Dixon, with a little bit more calmness, could have slipped a better ball across and we could have had a goal. We got some decent balls into the box but couldn’t take any of the chances, although to be fair, they were limited at both ends.”
Of Richards, who has been given permission by Swansea to play for Town in the Capital One Cup third-round tie at Hull tomorrow, Robins pointed out: “He looked a bit rusty, and needs a little bit more adventure.
“Defensively, he was up against a really quick player, but you didn’t see that in Josh Kane, so from that perspective, he did the job.”
Blackburn boss Bowyer said: “I think for long spells we dominated the game in terms of possession.
“Crosses and shots stats weigh heavily in our favour but we haven’t been cute enough in the final third.
“Huddersfield changed formation four times so that's a massive compliment to us.”
