James Coppinger says Doncaster's unique transfer policy, led by agent Willie McKay, was 'disrespectful' to the Championship.
Rovers were relegated to League One at the weekend despite bringing in a host of big names this term, including the likes of El-Hadji Diouf, Habib Beye and Frederic Piquionne.
McKay brokered a number of deals that saw Doncaster sign players on minimal wages, with the club used as a window for their talents.
But Coppinger has slammed the system, insisting it was to blame for their relegation.
"I think it's disrespectful to the league if you think you can just bring in big names and that will win you games," Coppinger said.
"In this league, and in leagues below, you need more than just names on the team sheet.
"You need passion, commitment and togetherness and it just shows sometimes if you haven't got that, you don't do anything in football.
"I've been here eight years and this is the hardest and most frustrating.
"The players that have been here a long time and had so much success in the Championship and kept us in the league for three years have found it difficult because it is a totally different regime and it hasn't worked out for us."
