Collaros' return is being forced by Brown's interception tax, not his yardage.

Collaros was limited Wednesday after two games on the six-game IL, but Dru Brown has averaged 250.3 passing yards per start vs. Collaros' 244.9. The gap is ball security: Collaros is 11 TD/6 INT (1.83) and 5-4; Brown is 8 TD/7 INT (1.14) and 2-4. That explains why O'Shea won't rule out a 38-year-old QB who hasn't played since the IL placement.
