The game was dead and buried with just seven minutes of normal time remaining, until the Millers staged the most miraculous of recoveries to earn a point.
Here's how the players rated, with your chance to add your own.
Lee Camp 9 - The Camp juggernaut of a season continued with a string of fine saves that kept the deficit to three.
Stephen Kelly 6 - Struggled on his first start since December against a very potent attacking unit.
Kirk Broadfoot 7 - Marshalled the troops well and was the stand-out performer on a difficult afternoon for Rotherham's defence.
Danny Collins 4 - At fault for the first and third Derby goals, it has been a difficult season for the veteran, who made his first start since December.
Joe Mattock 6 - Booked early on and had a difficult afternoon against the imperious Tom Ince.
Paul Green 5 - Restored to the side in the absence of Greg Halford, Green was overrun against his former club.
Richie Smallwood 7 - Battled hard and provided some resistance to wave after wave of Derby attacks.
Lee Frecklington 6 - The tiredness in Frecklington shone through, but he was at the forefront of Rotherham's late charge.
Jerome Thomas 5 - Cam off injured after 30 minutes having made no impact.
Matt Derbyshire 6 - Again asked to play out of position, he had little impact but worked hard.
Danny Ward 9 - Another wonderful display from Ward who worked tirelessly throughout and scored one and created another.
Grant Ward 6 - As usual, he added legs to Rotherham's midfield and created his namesake's goal.
Joe Newell 7 - Added a spark to the Millers attack and contributed to the Millers comeback.
Leon Best 8 - Could not have chosen a better time to break his duck for the club.
