Knill watched the Iron finish their campaign with a 1-1 draw at Tranmere, Garry Thompson levelling after Mark McChrystal headed the hosts in front to ensure it finished all square at Prenton Park.
"I enjoyed the second half. Some of the passing and moves were really pleasing," the United boss said. "We stuck at it and were pretty good. It was a great finish for the equalising goal.
"The fact their goalkeeper got the man of the match award sums things up really. I am pleased with the players and we are going to get better. The only times Tranmere looked dangerous were when we gave them the ball.
"I am lucky to have a group who want to be modern footballers and want to impress. But now I have got some tough decisions to make. It is one of the worst parts of the job deciding who stays and who goes. It is going to be a difficult Tuesday.
"We have progressed this season and hopefully we will surprise a few people next season."
