Brennan was one of the most prolific passers in NCAA history. He threw for over 14,000 yards, 131 touchdowns, and took Hawaii to the Sugar Bowl in 2007. He grew up a Raider fan in Southern California and can't believe he is now wearing the silver and black.
"The silver and black was a big deal where I grew up and like I said my first day, when they gave me my helmet I was like, 'Wow, this is kind of a surreal moment,'" says Brennan.
Brennan had four surgeries in his two years with the Washington Redskins, was released last week, and the Raiders scooped him up off the waiver wire. Coach Tom Cable likes what he sees in this young guy.
"If you watch him, he does a pretty good job of putting it on receives, leading them, timing it up over the top and he has a knack for some of these things," says Cable.
"I'm not afraid to throw it, you know, so that's one thing. I'm just looking to get offense down, make good decisions and just be successful," says Brennan.
Brennan is cramming to learn the Raider offense with help from his former Redskin teammate Jason Campbell.
"Jason helps with the playbook and he's just a good guy right up front and we were always friends," says Brennan.
With Bruce Gradkowski and Charlie Fry injured, Brennan will play Thursday against the Cowboys.
"I'm going to act like I know what I'm doing out there, no doubt about it. Maybe even if I don't, I'm going to act like I know what I'm doing," says Brennan.
Brennan may turn out to be a great deal for the Raiders.
