San Francisco, CA — Longtime 49ers great Joe Staley has always been known as a warrior on the field — but this week, fans got to see a different side of the beloved offensive tackle: a grateful student saying goodbye to the man who changed his life.
Staley’s childhood football coach and mentor, Richard “Coach Rick” Brennan, passed away peacefully in Michigan this past Sunday at the age of 92. In a heartfelt Instagram post accompanied by an old photo and a handwritten letter, Staley honored the man who, in his words, “taught me how to be a man long before he taught me how to block.”
“He saw something in me before I ever believed in myself,” Staley wrote. “Every time I put on pads, I carried a piece of his voice with me. Rest easy, Coach.”

🧒 From Humble Beginnings to NFL Stardom
Joe Staley credits Coach Rick with igniting his love for the game during their time at Rockford High School, where Brennan coached for over four decades.
- Coach Rick helped Staley transition from tight end to offensive line — a move that ultimately launched his NFL career.
- He remained a mentor and friend through college and Staley’s 13-year career with the 49ers.
- Even after retiring, Staley said he called Brennan after every season — just to hear “that voice that always brought me back to who I was.”
“Coach Rick never chased glory. He just believed in people. And I was lucky to be one of them.”
🕊️ The Legacy That Lives On

Fans, former players, and even NFL rivals commented on the post:
- “This is the kind of story that reminds you what sports are all about.”
- “Joe Staley — always class. What a tribute.”
- “Coaches like this never make the headlines. Thanks for making sure he got one, Joe.”
Staley concluded the post with a photo of his old practice jersey — with Coach Rick’s initials sewn onto the sleeve.
