Keep in mind, Trubisky was on a podium and behind a lectern where he had stood so many times in 2018 with youthful energy and charisma. He had chosen a Mike Ditka look there last October — Aviator shades, Bears sweater vest — to commemorate a 24-10 beatdown of the Jets the weekend before Halloween. He had worn a blinking Christmas sweater a couple of months later, a festive way to enjoy the Bears’ 24-17 division-clinching victory over the Packers.
