David Johnson was not on the field Sunday for what was arguably the biggest offensive play of the game for the Cardinals -- a third-and-2 at the Chicago 42-yard line with two minutes left in the game and rookie quarterback Josh Rosen trying to drive the Cards to a game-winning field goal. It was rookie Chase Edmonds who got the call on a run to the left that ultimately lost three yards. (Rosen was intercepted on the next play.)

Johnson said Monday he, or more specifically, his mistakes, were the reason he was not in on the play.

"The play before the third-and-2, I missed a blitz (pickup)," Johnson said. "I had to go to the sideline and talk to (running backs coach) Kirby (Wilson) about it, because I actually did not see the guy that was my guy."

Johnson said Wilson called him out of the game to talk about it, even in such a situation. To begin with, "I have full trust in Chase" to be able to run the play.

Additionally, "I want my coach to keep me accountable, I want my teammates to keep me accountable," Johnson said. "When I mess up, I want them to tell me, I want Kirby to tell me, (Steve) Wilks, (Mike) McCoy, what I did wrong."

Johnson lamented another blitz pickup error as well. "They expect me to be the playmaker, the guy who does everything he can, the guy they lean on," Johnson said.

Earlier Monday, Wilks was asked again about the third-and-2 play.

"(The issue) was up front," Wilks said. "I'm not one to point out any one guy, because it's all the guys up front. As a team, we talk about certain things -- it was just too much (defensive) penetration. I was very confident in the call, very confident in Chase being in there. As I said, we just have to do a much better job up front in terms of executing."

-- Wilks also said during his appearance on the "Bickley and Marotta" show on 98.7, Arizona's Sports Station that the timeout called by the Cardinals with 39 seconds left in the first half Sunday was a "miscommunication" and that he would take responsibility. It turned out not to matter, because after the Cards punted, the Bears chose to run out the clock anyway.
