Ever since Wesley Chapel offensive linemen Kamran Joyer asked for and was granted his release from the University of South Florida, there has been various accounts on why Joyer opted out of his letter of intent.

In Thursday’s Tampa Tribune and online at TBO.com, Tribune reporter Lindsay Peterson and I discovered that USF questioned why there were nine grade changes during Joyer’s senior year in high school. Robert Spatig, USF’s director of undergraduate admissions, outlined and questioned the nine grade changes in letters last month to Pasco school Superintendent Heather Fiorentino and Wesley Chapel High School principal Andrew Frelick, wondering if he received “special consideration” because he was an athlete.

The NCAA is also investigating, Spatig said in his letters to Pasco officials.

Because of Spatig’s concerns, Pasco County’s School District launched an investigation into all incoming freshmen headed to USF to make sure all of their grades were assigned appropriately. A Pasco County official said all students would be admitted as planned, but that the school district is still investigating how Joyer’s grades were changed.

Joyer, by the way, is visiting Louisville today and was expected to sign with the Cardinals, his father, Jack Joyer, told me Tuesday.
