MITCHELL TRUBISKY'S POSTGAME media conferences are mind-numbing exercises in amiable banality. He greets every question with a cheery and time-buying "For sure" and then proceeds to break it down to its least interesting parts. This is by design -- he'd never allow himself to give anything away. Apart from the crowd, Trubisky describes football and his Chicago Bears teammates and coaches and their bond -- the whole sprawling, messy lot of it -- as "a sacred obsession." And he sees himself, the quarterback, as the keeper of that trust.
He exists within a self-enclosed and self-defined space that eliminates outside influences.
