ENGLEWOOD Case Keenum Color Rush Jersey , Colo. (AP)Broncos coach Vance Joseph is going with experience this time, hiring Tom McMahon to replace Brock Olivo as his special teams coordinator. Joseph gave Olivo his first shot at coaching special teams last season, but Dave Toub’s longtime assistant in Kansas City oversaw one of the worst special teams in the league and was among six assistants Joseph fired last week. Rookie punt returner Isaiah McKenzie fumbled six times but kept his job for most of the season, a sore spot with several veterans who felt there was a sense of privilege among the members of the 2017 draft class. Olivo’s units had trouble getting the right personnel onto the field, twice telegraphing trick plays because of it, and they were even whistled for delays on kickoffs . Denver’s special teams gaffes led to 24 points by the Patriots in New England’s 41-16 win in Denver on Nov. 12 and Joseph drew criticism the next day for sticking with Olivo . However, Olivo was one of six assistants fired after a hugely disappointing 5-11 season when Joseph said he needed to ”change the culture” on offense and special teams. McMahon is a 26-year coaching veteran who has coached NFL special teams for the last 11 seasons Jared Veldheer Jersey , including the last five in Indianapolis, Kansas City in 2012 and St. Louis from 2009-11. The Colts featured one of the league’s most consistently solid special teams units during McMahon’s five seasons in Indianapolis. He became available after the Colts fired head coach Chuck Pagano last week. Joseph praised McMahon’s ”direct teaching style that emphasizes fundamentals,” noting he `has a proven track record developing young players on special teams that will bring leadership and energy to this important phase of our team.” Joseph also promoted Chris Strausser to coach the offensive tackles and hired ex-Colts assistant Greg Williams to coach defensive backs and ex-Bears assistant Zach Azzanni to coach wide receivers. Strausser, who was an assistant offensive line coach under Jeff Davidson last year, will coach the tackles with Sean Kugler coaching the guards and centers in a new setup along the O-line, which has been the Broncos’ bugaboo going back to Peyton Manning’s time in Denver. Last year’s first-round draft pick, left tackle Garett Bolles Connor McGovern Color Rush Jersey , was among the league’s leaders in penalties and often allowed an early mistake to affect him and the team adversely the rest of the game. — MIAMI (AP)Coach Adam Gase’s new backup quarterback in Miami is his former backup quarterback in Denver.Brock Osweiler signed a one-year contract Friday with the Dolphins to provide veteran insurance behind Ryan Tannehill, who is coming back from two knee operations.Gase was an assistant with the Broncos when Osweiler was a young reserve for them in 2012-14.
