Definitely could tell he was playing with some kind of injury, as he just didn't look comfortable on the field. That being said, he played pretty well against the Vikings. He's definitely someone who will get some rest if Dallas wraps up the 1 seed early.
For those who are saying drop him, do y'all even look at the cap when you make these assertions? He's not droppable for several more years. In 2-3 years he'll just be our slot corner, which will be overpaying for him, but a cheap Anthony Brown contract will help offset that a bit.
