Clay Matthews III comes from a long line of football excellence.
His grandfather, Clay Matthews Sr., played tackle in the NFL in the 1950s.
His dad, Clay Matthews Jr., was a Pro Bowl linebacker during the 1980s.
It may be hard to believe now that Matthews III sports some of the beefiest biceps in the NFL, but he was a relative pipsqueak during his early days at Agoura High School (Agoura Hills, California).
Though his father was the team's defensive coordinator, he did not start his son until his senior year due to Clay being so undersized.
Between his junior season and senior season, Clay dropped 0.4 seconds off his 40-Yard Dash and packed on almost 50 pounds.
Though he played more as a senior, he was still a relative nobody in the recruiting world.
Matthews decided to walk on at USC, and he went on to be a first-round pick in the 2009 NFL Draft. Now a linebacker with the Green Bay Packers, Matthews boasts six Pro Bowl selections.
"I don't think I'd be in the position I'm at today if it weren't for all the setbacks and whatnot, people telling me I couldn't do it," Matthews once told Boston.com. "It's kind of what drives me to be great."
