The name of the stadium is Pat Catan Stadium. The previous location of the high school football field was at Center Middle School . The stadium was featured on national television when the Mustangs took on the Glenville Tarblooders in 2006.

Court case
In January 2006 a male former Strongsville High student sued the school district and the police department claiming that they did nothing to stop an affair he had with a female teacher while he was a student at the school. The teacher concerned was put on probation.
