Clemson admitted that its football program has broken NCAA rules since 1984, but the school said the violations were either isolated or unintentional and did not create a competitive advantage.

The confession was included in a synopsis of Clemson’s written response to allegations levied 2 1/2 months ago by the NCAA that the school’s football program violated a number of NCAA rules.

In a letter accompanying the report, university President Max Lennon said Clemson’s internal investigation determined that some of the allegations are true. But he said many of the charges were not substantiated.

Of the 13 charges of rule violations, Clemson admitted to six violations involving recruits but said they were inadvertent, and said three others were only partially correct. The university said it could not substantiate two violations and thought two others did not occur.
