"Marvin and I had a great three years together in Baltimore. I've known him a long time. We were together back in 1999, 2000, 2001, won a World Championship with him, so yeah, we've remained good friends. He's a good friend and a really good coach, and looking forward to going against him Sunday."
The Cincinnati wide receivers will provide the Raiders secondary a good test, but Head Coach Del Rio made sure to note that each week in the NFL is a test in its own right.
"It'll be a good test. Every week there's a good test. We'll talk about the talent on the other team every week. Everybody has talent in this league, certainly they have talent and we're looking forward to matching up."
He also spoke about the expectations for rookie wide receiver Amari Cooper heading into his first regular season game.
"He'll just get himself ready to play. Prepare himself, and go compete and play hard. That's all we expect of him. That's all we want him to do, and that's the way he's wired anyway."
The Silver and Black open the season at home, and Head Coach Del Rio spoke about the importance of starting the season out with a positive result.
"I think it's important to win at home. We've got great fans that are going to come out in full force on Sunday, and we want to put on a good show for them and make sure they're proud."
