So when the Eagles drafted his brother, Oregon linebacker Casey Matthews with their fourth-round pick (No. 116 overall), fans were quite pleased.
But Casey has some news for those fans: He's not Clay. And that may be a good thing.
"I'm my own man," Casey said. "Obviously what they've done motivates me, but I'm trying to reach a level they haven't reached. I know it's going to take a lot of hard work but that's my goal. Again, like I said, I'm my own player. I'm just looking forward to competing, not being known as Clay's little brother and be known as Casey."
Clay played outside linebacker for the Packers, while Casey played middle linebacker last season while leading Oregon to the BCS National Championship game. Casey had 73 total tackles, three interceptions and one forced fumble in 2010 for the Ducks.
"I believe my instincts are better than his," Casey said. "He's more of an explosive athlete. He has more explosion, but that's what it takes to be an outside 'backer. Being an inside 'backer, you have to get people lined up. Inside 'backers have a lot of instincts – being able to read the play, being able to get to where to ball is going quick."
Casey has the genes to be successful in the NFL. Besides his brother, his father (Clay Jr.), uncle (Bruce) and grandfather (Clay Sr.) each played in the league. Casey said that after visiting with the Eagles before the draft, he realized this was a place he wanted to be.
"I went out there on a visit and I knew that it was one of the teams I wanted to go to," Matthews said. "It's a dream come true. They drafted me (and) I'm looking forward to getting out there and just being a part of a team that wins."
Matthews said that his football philosophy meshes well with that of the Eagles defense.
"Just the way they attack," he said. "My defense in college was similar, attack (with) the linebackers, bring them downhill. I'm looking forward to learning the system and getting involved in it anyway that I can."
Despite his yearning to be known for his own play, Matthews admitted that there are similarities between how his brother Clay plays and how he approaches the game. It's a family trait that may just endear him to Eagles fans.
"A constant motor, that's one thing we both have," Matthews said. "Even when the play was away, the best opportunities to make plays (are) just by running to the ball. You never know what's going to happen. Obviously we (play) different positions. We're different types of players. In regards to motor, that's where we're similar. Also, just our overall knowledge. We had my dad as a coach and that really helps us out picking up schemes and our overall football I.Q."
