Prior to donning the Silver and Black each Sunday, many of the Raiders players were wearing different colors on Saturdays, playing for their college teams and representing their respective universities.
This time of the year in particular college rivalries run deep, so we're here to highlight some of the matchups between current Raiders teammates, but former college football foes.
Charles Woodson's Michigan Wolverines vs. Jon Condo's Maryland Terrapins at Byrd Stadium in College Park, Md.
In case you haven't heard, there's a new man running the Maize and Blue in 2015 – former San Francisco 49ers head coach, and one time Raiders quarterbacks coach, Jim Harbaugh.
After dropping their first game of the Harbaugh Era 24-17 to the Utah Utes, the Wolverines have won their last three contests and enter their showdown with Maryland coming off a 31-0 thrashing of the BYU Cougars and ranked at No. 23 in the AP Poll.
Conversely, the Terrapins enter Big Ten play coming off a 45-6 loss to the West Virginia Mountaineers and are looking to notch a win in their conference opener.
In another interesting twist, the game, which was originally scheduled for 8 p.m. will be moved up to noon as a result of inclement weather from Hurricane Joaquin.
A Walk Down Memory Lane:
Woodson:Where to begin with Woodson's college career?
For starters, he was named a starter in the second game of his freshman year, playing in 34 straight games before electing to turn pro.
During his time as a Wolverine, Woodson became the first predominantly defensive player to win the Heisman Trophy, and was also named a two-time All-American, Chevrolet Defensive Player of the Year, a three-time All-Big Ten selection and was named the MVP of a 12-0 team that won the 1997 Associated Press National Championship.
Not bad for the kid from Fremont, Ohio.
Condo:While he played at Maryland, Condo majored in science education and was the long snapper for the Terrapins for 38-straight games.
He helped the team earn Orange, Peach and Gator Bowl berths and became the first pure long snapper to earn Maryland's top special team honor.
Condo admitted to not being one for predictions, but said that he's anticipating a good game Saturday.
"I'm not sure," Condo said. "It's still young in the season. It's hard because it's the first Big Ten game of the year. Maryland beat them last year, but every year is different."
