Former Miami Dolphins guard Bob Kuechenberg William Hayes Jersey , a six-time Pro Bowl selection and member of the only NFL team to achieve a perfect season, died at age 71.His death Saturday was confirmed by the Dolphins, who had no further details.Kuechenberg joined the Dolphins as a free agent in 1970, coach Don Shula’s first season, and played for them until 1983. He started every game for the team that went 17-0 in 1972, and started 16 games for the team that repeated as Super Bowl champions in 1973.Kuechenberg was a finalist for the Pro Football Hall of Fame and a member of the Dolphins’ Honor Roll.“I was sorry to learn of the passing of Bob Kuechenberg, who was not only one of the best players I ever coached but one of the toughest as well,” Shula said in a statement. “He was one of the key performers on our championship teams.”More Miami Dolphins newsDolphins Akeem Spence Jersey , veteran LB Mike Hull agree to terms on 1-year contractThe next stop: Ryan Fitzpatrick moves into starting QB role with Dolphins, for nowDolphins sign former Jaguars guard-center Chris ReedDolphins sign QB Ryan Fitzpatrick to two-year, $11 million dealEnd of the road: Dolphins trade QB Ryan Tannehill to Titans for picksShula said Kuechenberg played with a broken arm in the 1974 Super Bowl and still dominated Hall of Fame defensive tackle Alan Page as Miami beat Minnesota 24-7. That game was 45 years ago Sunday.Former teammate Jim Langer, a Hall of Fame center, said he stayed in touch with Kuechenberg, spoke with him in the past week and was shocked to learn of his death.“He was the kind of guy you’d want in your foxhole,” Langer said. “He played hard and was very intense about the game, which was typical of our team. He was my roommate for 10 years A.J. Derby Jersey , and we talked football damn near all the time.”A native of Gary, Indiana, Kuechenberg played at Notre Dame before being drafted by the Philadelphia Eagles in 1969 but never played for them. Kuechenberg’s 196 games with the Dolphins was a team record until Dan Marino broke it. The Dolphins parted ways with their two leading sackers from last season and they haven’t brought in any edge rushers to fill the spots left open by Robert Quinn and Cameron Wake.Miami’s pass rush wasn’t overwhelming with those players and the current makeup of the defense hasn’t led to many predictions of a big jump in productivity. On Thursday, though, defensive coordinator Patrick Graham downplayed the personnel side of things.Graham said he was confident the team had enough pieces to build an effective pass rush and stressed the role the coaching staff will play in making sure those pieces are successful.“The beauty about the pass rush, and I’ve always said this, is it’s very fluid,” Graham said at a press conference. “Everything is very fluid. As you watch it and you try to get an understanding of it Josh Sitton Jersey , you can take advantage of it in different ways, different shapes, different forms and different people. It doesn’t always have to be the cookie cutter idea that people have of a 6-foot-5, 250 pound whatever who runs a 4.5. That doesn’t necessarily mean that’s going to automatically guarantee you pass rush success. To me, pass rush success is us game-planning it, the players executing it and us trying our best to affect the quarterback.”Graham and Dolphins head coach Brian Flores both have experience working with Patriots teams that have rushed the passer well without having the prototypical stars coming off the edge. It looks like they’ll need to repeat that trick if quarterbacks are going to feel uncomfortable against their defense this season.
