McCoist's side were booed off after being held to a goalless draw by Stirling, affirming Rangers' recent poor form that has seen them win only two of their last five games.
And the manager has warned the young players that they must produce more to meet the demands of the Ibrox fans.
"I've explained to them - that's what it's like being at Rangers," McCoist said. "You just have to find something from somewhere.
"The younger lads, Robbie (Crawford), wee Barrie McKay, Airdy (Fraser Aird), Kyle Hutton, Kane Hemmings and boys like that, for a first season, generally speaking, they have played a lot more games than they would have before.
"They have done okay but they need to progress, they need to keep coming along.
"That was a disappointing performance and result but - do you know something? - it's a point, a hard-earned point which will hopefully help us over the line."
McCoist added: "The people in the stands, we all share their frustration. I can totally understand their frustration and I can't ask for anything more from the stands than they are giving us in terms of support.
"I know more than anybody at this football club what it's like to play here and the level of expectancy.
"That will not change, although there is absolutely no doubt that the team has changed more dramatically in 12 months than it has done in its entire history.
"But the expectancy is still very, very high and I understand that."
Midfielder Crawford, understanding fans' frustration, said: "I totally understand their frustration and we all feel it as well.
"It hurts us just as much and the fans have the right to voice their opinion. They have stuck by us before and we need to do better for them.
"There was a lot of youth and not much experience there but we have all come through the youths together so we should know each other's game and we expect to play better than we did."
