Debutant DJ Campbell came off the bench to snatch a draw for Millwall with a header 10 minutes from time after second-half substitute Giles Coke had put the visitors ahead.
Shane Lowry and Coke both saw red late on for an altercation in the corner, but Holloway insists he has seen an improvement in the attitude of his side that will warrant a change in fortune.
"I saw a little bit of nervousness, which is understandable because of what has happened this season," he said.
"I saw a lack of understanding which comes from the team structure and team mentality and because they played with a different shape to what they have in the last four or five games.
"Unfortunately the way things are going we went one-down, but I was delighted because the spirit we have been talking about came, the togetherness came and we got excited about what we were doing.
"In any boxing match if you ask them you'll know if the other bloke was a bit better than you and they damn well know that so for me that is a moral victory.
"We need points, but where this group would have failed a couple of weeks ago a with a lack of spirit they are raging with that energy they have and we are getting better."
