When the Bears’ starting offense hardly played in preseason games in 2019 — with Mitch Trubisky taking three snaps without throwing a pass — its sluggish performance in a 10-3 loss to the Packers in the regular-season opener was so stark that even coach Matt Nagy acknowledged the error and vowed to try a different tack in 2020.
‘‘I look back and I say if I could change something in 2019, it would be playing our starters more — 100%,’’ Nagy said in May 2020.
