A 77th-minute header from Leon Clarke rescued a point from a home clash with Brentford, after the hosts had missed a penalty then taken the lead through Harry Forrester.
The point left Knill's side rooted in the League One relegation zone, though the point did halt a three-game losing streak.
"This is not where I want us to be. I feel for the supporters at the moment. They turn up wanting to see us do well and be entertained," he said.
"And it's only us who can effect that and the only way we can do that is to go out and be brave and be positive."
Knill acknowledged that Brentford had been the better team in the early stages.
"When they went in front, I am sure not many people expected us to get back," he said.
"But when things were not working for us, we had to make some changes to the way we played.
"We did that, we got back on level terms and I then expected us to go on and win it.
"But then we have a player sent off, and it makes it difficult for us again. This was a game it was important for us to get something out of and it is credit to the players that we have. It gives us something to build on, to go forward again."
Uwe Rosler, the Bees boss, told his side they must be more ruthless if they are to challenge for promotion.
"This was a game we should have won, Scunthorpe were never in control of it," he said.
"But I have been saying the same thing now seven or eight times this season. It was a good performance but once again we have failed to kill the game off.
"We have a talented young squad of players who I am excited to be working with. What we lack is a bit of experience and that can be frustrating, but the budget we have dictates what we have to work with."
