Barnsley manager Keith Hill blamed a lack of finishing and poor defending for his side's 2-0 defeat at Derby.
Hill was left to reflect on what might have been after Stephen Dawson wasted a great chance just before Nathan Tyson sealed victory in the 90th minute following James O'Connnor's opener.
"We give the opposition to much encouragement with silly free-kicks but it's marginal whether you win, lose or draw depending on the decisions players make," he said.
"I set a framework out but the players have to make decisions within that. The players have given me everything they possibly could but when we create chances we've got to convert or at least hit the target and when we defend free-kicks we've got to make sure we clear them.
"The players have got to make better decisions on behalf of me and I can't play that game for them. We are looking for them to progress by making less mistakes and to be more assertive in front of goal."
