Wiederer: Let's not forget the two biggest personnel moves of the weekend — the addition of guard Josh Sitton and the Connor Barth-for-Robbie Gould kicker swap. And with a best-case scenario slant, maybe this means Sitton retains his Pro Bowl-level production and learns the offensive system fast enough to be a major difference-maker in September. Maybe his presence also sparks Whitehair's ascent as Ryan Pace is hoping it will. And maybe Long's left shoulder injury doesn't hinder his play all that much. Voila! Just like that, the Bears might be able to boast one of the best interior line trios in the entire league.
