The Bears collected several shiny new weapons in free agency and the draft to surround Mitchell Trubisky. But not everyone helping the young quarterback grow catches passes or throws blocks.
First-year offensive coordinator Mark Helfrich and returning quarterbacks coach Dave Ragone both figure to be instrumental in Trubisky's development.
Helfrich operated some of the most explosive offense's in college football history at Oregon, first as offensive coordinator (2009-12) and later as head coach (2013-16). In 2014, Helfrich helped quarterback Marcus Mariota become the school's first Heisman Trophy winner.
"He's a people person and he also has a sense of humor, which not everybody knows," coach Matt Nagy said of Helfrich.
