Chesterfield manager Paul Cook offered no complaints following his side's 1-0 defeat against local rivals Rotherham at New York Stadium this afternoon.
The Spireites fell eight points adrift of the League Two play-off places after Johnny Mullins' 58th minute bullet header ensured all three points remained in Yorkshire.
The visitors never really got going in the contest, with Sam Togwell's late goal disallowed for offside the closest they came to snatching a point.
Drew Talbot and second-half substitute Armand Gnanduillet both glanced headers wide in stoppage time, but the Millers held on for a deserved victory.
"We got away with murder, it should have been more," a disappointed Cook lamented at full-time.
"We did not turn up in any shape of form. Listen, I don't want to be too critical and say stupid things. The best team won comfortably, we built up a head of steam late on but it was out of embarrassment because of how bad we were.
"I take the blame for everything, I have got no problem with that but players need to stand up now and again.
The home side flew out of the traps and former Manchester United striker Daniel Nardiello threatened inside three minutes when he breezed past Liam Cooper before thumping the foot of the post with Tommy Lee beaten.
Chances remained at a premium thereafter, until strike-partner Alex Revell somehow contrived to miss when he raced clear through immediately after the restart.
Nardiello then blazed a free header over the top, but Millers' skipper Mullins made no mistake with his header when he got up to slam home a bullet two minutes before the hour and move Steve Evans' side just a point behind the automatic promotion spots with a game in hand.
"It was coming, no matter. You can dress it up as the manager but they were going to score.
"What we weren't prepared to do is wait for them to score to make a change, but whatever we tried was not good. We weren't good at passing, we weren't good at being direct.
"Every credit to Rotherham, they were a handful from the first minute. It was pure luck why we went in at half-time 0-0. The likelihood is that you want to change it at half-time, but you think well can they keep it up and can we play any worse?
"We let our supporters down, but I'm being brought in to do a job and I think they trust me."
It was the Spireites' first visit to New York Stadium and with over 2,300 packed behind the goal, Cook was disappointed that he couldn't send an impressive travelling contingent back to North Derbyshire with bragging rights.
"You have got to have desire and pride.
"You can't turn up in a local derby and expect it to happen. I carry the can for us today, I am the leader of this group and we weren't good enough. I wish we hurt like the supporters. We have got some lads that feel the pain but we don't have enough by any stretch of the imagination.
"It would have been an injustice on Rotherham today, fair play to them they were on the front foot for the full game. At times, we couldn't handle them and that's sad.
"You can talk forever, but you will just bore people in my opinion. Let's just hurt and if you're not hurting, do us a favour and let someone else come in."
