None, USC Quarterbacks do not make it in the NFL.
The University of Southern California (USC) has historically placed more quarterbacks in the NFL than any other NCAA football program. Notable USC quarterbacks include Carson Palmer, Matt Leinart, and Sam Darnold, among others. This legacy of producing NFL talent at the quarterback position has solidified USC's reputation as a premier program for developing professional-level quarterbacks. Other programs, like the University of Oklahoma and the University of Florida, also have strong quarterback pipelines, but USC leads in overall numbers.
