As probably hoped back in April, the Bears' long-term answer at left tackle may be in place now.
Before Week 12, Chicago Bears rookie offensive tackle Ozzy Trapilo had played 72 offensive snaps this season and exactly one of them (according to Pro Football Focus) came at left tackle. But he stepped and made his first NFL start protecting Caleb Williams' blindside against the Pittsburgh Steelers that Sunday, and he acquitted himself very well (one pressure and no sacks allowed).
