When Kansas City Chiefs special teams coordinator Dave Toub first came to the team in 2013 after nine seasons doing the same job with the Chicago Bears, Kansas City special teams were immediately among the league's best, repeatedly scoring touchdowns on kickoff and punt returns.
Through 2016, his units scored nine touchdowns — while allowing none by opposing teams. Starting in 2017, the rate of kickoff and punt touchdowns began slowing down. Many observers started to say that Toub had lost his edge — that was no longer running the league's best unit.
