Knill saw his side miss out on automatic promotion on the final day of the season and then crash out of the play-offs on penalties.
He said: "We are not the finished article. We've had a fantastic season but we need to progress.
"This season is done now, we can all look forward to next season and step on.
"I can only play football one way, I am a coach with young players.
"I want them to have the ball and I think that's the only when that they are going to get better. It's easy to get the ball at the back and launch it but I owe them to teach and that's what I will do."
