Winston is an experienced veteran. He's started, cone off the bench and done it all before. And he's gotten plenty enough snaps to know how to come in and do what he does.
And who's excusing Carr? He was meh at best yesterday before his injury. Ultimately, I think we all realize the coaching staff is gonna ride or die with Carr. They've already committed to him for the duration of the season unless an injury rules him out. It is what it is.
