Disagree. He isn't playing in place of Chandler Jones in sub against a passing team. Jones is a far better pass rusher.
In sub, he doesnt really have a play to play (Nink,DT,DT,Jones,HT, Collins) until we get to 3rd and long and bounce Jones inside.
In base, it is very surprising to me that Casillas has played ahead of him, although it could have been a chance to see what Casillas could do in the buff game, which by the way, was play horribly.
I would assume Ayers has his job back if and when we ever play base, and in sub is the first backup off the bench at DE or LB.
