Haloti Ngata — Oregon (Pac-12) (2003-2005)
Oregon has produced two Hall-of-Fame quarterbacks, Norm Van Brocklin and Dan Fouts, but Haloti Ngata has to be the greatest Duck ever. In 2005, the standout defensive tackle was a unanimous All-American. In the NFL, Ngata was drafted 12th overall by the Baltimore Ravens in 2006 and he spent almost all of his career with the team. Ngata won a Super Bowl, was named to five All-Pro squads, and was a five-time Pro Bowler. In 2019, he announced his retirement, capping off a professional career which will probably earn him a spot at the Hall of Fame.
Chad Johnson — Oregon State (Pac-12) (2000)
While Oregon State has not had plenty of players go on to do a lot in the pros, Chad Johnson definitely did. In 2000, he transferred to Oregon State and played only one season, although he lit it up, something that he continued to do in the NFL. His pro career was mostly spent with the Cincinnati Bengals and he made headlines for being an outstanding wide receiver and for his larger-than-life personality. He made six Pro Bowls and was a four-time All-Pro, including a three-time first-team.
