Clay Matthews turned 60 years old Tuesday, marking a milestone for the legendary Browns linebacker.
But it wasn't that long ago when Matthews was terrorizing opposing quarterbacks and offenses en route to one of the most distinguished careers in Browns history.
In this week's edition of Throwback Thursday, we look back on Matthews and what he meant to the Browns and professional football.
Matthews, who played in the league for 19 (19!) seasons -- including his first 16 with Cleveland — became a staple of the Browns organization for his relentless style of play, big hits and lighthearted personality off the field.
The first-round draft pick in 1978 was a beacon of consistency, playing in 278 games, the 17th most in NFL history.
Here's a by-the-numbers account of Matthews' career:
12 — Matthews was the 12th overall pick by the Browns in 1978. Cleveland also drafted Hall of Famer Ozzie Newsome the same year with the 23rd pick.
1,561 — That's how many tackles Matthews made in his career. It comes to about an average of 83 stops a year. It's also the third most in NFL history.
232 — Matthews played in 232 games with the Browns from 1978 through 1993. That's a franchise record.
4 — Matthews played in four Pro Bowls (1985, 1987, 1988, 1989)
3 — Matthews was an All-Pro selection three times (1984, 1988, 1989)
1990 — On Jan. 6, 1990, Matthews sealed Cleveland's dramatic, 34-30, win over the Bills in the playoffs by intercepting Buffalo QB Jim Kelly in the waning seconds of the game. The win sent Municipal Stadium into a frenzy and goes down as perhaps one of the biggest plays in franchise history.
2002 — Matthews was inducted into the Cleveland Browns' Legends Program.
