The Oakland Raiders used to play in the Los Angeles Coliseum. Their top two quarterbacks for 2012 are set to be two Heisman Trophy winners who starred there at the University of Southern California.

ESPN reports free agent Matt Leinart will sign with the Raiders to be the backup to the man he succeeded under center at USC, Carson Palmer. The move also reunites Leinart, who played in Houston last season, with former Texans quarterbacks coach Greg Knapp—the Raiders' current offensive coordinator.

The addition of Leinart means second-year quarterback Terrelle Pryor will be demoted to third string.

Leinart made one start for the Texans last season, filling in for injured Matt Schaub. But he ended up breaking his collarbone in that Nov. 27 game against the Jacksonville Jaguars and joined Schaub (foot) on the sideline for the final month of the season.

Palmer won the Heisman in 2002. Leinart won it two years later and trumped Palmer's time at USC by leading the Trojans to back-to-back national championships under Pete Carroll.

USC's current starting quarterback, Matt Barkley, is a preseason Heisman favorite for '12 and is projected to be the top quarterback prospect in next year's draft.
