First, Reggie Bush got his Heisman Trophy back.

Now, his No. 5 will be forever honored by his alma mater.

He isn't the only one, as it was revealed Thursday that USC's football program is retiring Bush's No. 5 and Caleb Williams' No. 13. Both players won the Heisman Trophy during their collegiate careers with the Trojans.

Bush was one of the most electrifying college football players in the sport's history and was known for his ability to leave defenders grasping at air with his speed and agility. His resume at USC included two Pac-10 Offensive Player of the Year awards, two consecutive All-American selections, the Doak Walker Award as the nation's top running back and the 2005 Heisman.

He finished that season with 1,740 yards and 16 touchdowns on the ground to go with 37 catches for 478 yards and two scores as a receiver.

The star running back was a major reason USC reached the national championship game, although it was unable to defend its title thanks to a loss to Vince Young and the Texas Longhorns.

However, part of Bush's story includes his post-college career, when the Heisman Trophy was stripped away after the NCAA determined he and his family were given money and other gifts. Yet he filed a defamation lawsuit against the NCAA and said he was never paid to play at USC.

There has also been plenty of support for Bush to receive his Heisman Trophy back in the current name, image and likeness era of college football where players have the opportunity to make money even during their playing days.

With that as the backdrop, the Heisman Trust officially reinstated his 2005 win in April.

Williams is also part of that Heisman legacy at USC, as he took home the coveted individual award in 2022 by completing 66.6 percent of his passes for 4,537 yards, 42 touchdowns and five interceptions while adding 382 yards and 10 scores on the ground as a runner.

He was one win away from leading the Trojans to a Pac-12 title and the College Football Playoff but suffered a hamstring injury that limited him during a loss to Utah in the conference title game.

Williams returned the following season and was once again excellent while completing 68.6 percent of his passes for 3,633 yards, 30 touchdowns and five interceptions.

It was enough to convince the Chicago Bears to select him with the No. 1 overall pick in the 2024 NFL draft, and he will now look to become the dominant franchise quarterback the team has always been missing.

If he does, perhaps he can have his number retired in the NFL one day as well.
