The are at least as their quarterback moving forward, but all indications are that their signal-caller will be surrounded with new faces in 2020., the Bears have fired offensive coordinator Mark Helfrich, as well as three other a sistants -- offensive line coach Harry Hiestand, Justin Anderson Jersey tight ends coach Kevin Gilbride and a sistant special teams coach Brock Olivo -- in the wake Hal Greer Jersey of a tumultuous 2019 season.Both Trubisky and head coach Matt Nagy, a highly touted offensive mind following Chicago's 12-4 finish and playoff appearance in 2018, drew much of the criticism for the Bears' regre sion. But Helfrich, Hiestand and Gilbride also all had a direct hand in the team's offense, which ranked 29th in both yards and points per game a year after the club Maurice Cheeks Jersey boasted a top-10 scoring unit.A longtime college coach before joining the Bears in 2018, Helfrich helped oversee Trubisky's first Pro Bowl season during his Chicago debut but couldn't keep the former first-round draft pick from taking a big step backward in 2019. The Dikembe Mutombo Jersey ex-Oregon head coach didn't call plays under Nagy, who also arrived ahead of Trubisky's second NFL season, but he also garnered criticism for his part in the Bears' poor ground game, which saw rookie devolve into a non-factor throughout the year.Hiestand's O-line was also a problem for much of the 2019 season, whereas Gilbride's TE group relied mostly Isaiah Joe Jersey on reserves with top targets like perpetually banged up.
