Never fun for the General Manager to do his weekly radio appearance after a bad loss like Sunday's in Detroit, but there was Steve Keim on the "Doug and Wolf" show Monday morning, reiterating a lot of what we already knew: Carson Palmer played poorly, as did the team. He was actually OK with the defense, putting most of the end-game Lions scores on short fields and stamina after the offense had its bad game.

He had no update on the injuries to running back David Johnson (wrist) or left tackle D.J. Humphries (knee). Both are getting MRIs today. He said Humphries walked out of the stadium Sunday night so "who knows?" He said he couldn't base anything coming off the information they had last night, and it would be "hard to forecast" if either had any shot at playing Sunday in Indianapolis. Various reports don't have great news in that regard for either player. Hopefully Bruce Arians will have more when he talks at 12:15 today.

UPDATE: The news on Johnson was not good.

-- Keim said the Cards came in with goals this season, four of which being better in the red zone, eliminate turnovers, improve special teams, and execute better by playing smarter. Keim thought the special teams was OK -- although he knows Phil Dawson can't miss a field goal -- the Cards failed in those other areas.

"You can't win like that," Keim said. "Every time we had a chance to accelerate momentum, we shot ourselves in the foot."

-- Keim said when watching the film, he is "trying to be real" and wanting to be honest not only with himself but when talking to Arians and team president Michael Bidwill. Honestly, he said, a lot of things were disappointing. (Which may be an understatement in itself.)

-- Palmer has to play better. "I don't think it's any secret Carson was off," he said. Keim said Palmer usually bounces back after a game like that. Keim thought Palmer looked antsy in the pocket (I'd concur) and, like I mentioned yesterday, Keim brought up those few out routes that should have been completed on the sideline. Those are mechanical issues that can be fixed, Keim added, but need to be completed. Palmer also made some poor decisions.

-- The running game wasn't much better. Backup left tackle John Wetzel "had his struggles." While the offensive line has to be better, Keim noted that Palmer also held the ball too long at times and reiterated that the passing game/pressure on Palmer, is subject to the entire offense executing. "They all have to work in unison together."

-- Keim liked what Haason Reddick flashed but also talked about the pressure and missed sacks, because Reddick had one. Chandler Jones could've had four, Keim said.

-- Keim didn't want CB Justin Bethel getting beat deep on the last touchdown. But he also brought up, on the defensive side, similar discussion about working in unison. Bethel allowed on third-down conversion when Stafford escaped the pocket and moved left. Keim said linebacker Markus Golden was supposed to loop outside on the play and have contain on Stafford's left. Had he done that, Keim said, Golden would've had a sack or at least forced Stafford to throw it early. Instead, Golden stayed inside and Stafford could wait for the receiver to get away from Bethel.
