Harbaugh discussed Willis’ Hall of Fame induction in an interview with NBC Sports Bay Area’s Matt Maiocco on Friday at Super Bowl Radio Row.
“Talking about one of the great competitors,” Harbaugh told Maiocco. “I mean one of the toughest warriors that the National Football League has ever seen. I saw the x-rays of his hands, of his feet after the 2014 season. ‘How are you doing this? How are you able to play?’ You go back and look, he played with a club on one or both hands, I bet over 50 percent of the time. From [his] college days to the NFL. Screws in the feet, scar tissue, healed fractures – in every part of his hands and feet.”
Willis notoriously was a tough player and a staple of the Harbaugh-led 49ers teams. Throughout his eight-year NFL career, Willis was a seven-time NFL Pro Bowl selection and received five All-Pro honors.
Hanging up his cleats in 2014, Willis finished with 950 total tackles, 20.5 sacks, eight interceptions and two touchdowns. He started all 112 games he played in.
