Collaros's return after four games is the real transaction — not just a QB switch

Zach Collaros missed four games after a July 5 hit by Reggie Stubblefield, and Dru Brown went 2-2 as the starter in that span — wins over Toronto and Ottawa, losses to Calgary and B.C. The bye week also brought back right tackle Jarell Broxton and defensive tackle Cam Lawson, so the 4-4 roster that returns is healthier than the record suggests.
