There is no need for the grounds crew to slide the entire 100-yard football field inside University of Phoenix Stadium on Monday when the Cardinals resume training camp practices.

Twenty yards or so will do just fine at least for the offense.

That’s the part of the field that’s given the Cardinals problems in the first two preseason games. And although they beat the Cowboys 12-7 on Saturday afternoon the red zone was a dead zone for the Cardinals.

They failed to score a touchdown on five possessions inside the Cowboys’ 20 including four times in the first half. As a result they led just 9-0 at halftime despite running 49 plays and the Cowboys committing five turnovers.

This does not sit well with coach Bruce Arians who sees himself as a play caller who will go for the throat.

On Saturday sometimes you couldn’t tell where the Cardinals were aiming.

“Just like last week we play extremely well all over the field until we get inside the 20” Arians said. “Then we have a ton of mental errors. It baffles me. With all three groups we had mental errors in the red zone and ended up with field goals.”

One possession ended with an incompletion on third down at the Dallas 7. Jay Feely made the 25-yard field goal.

Another possession ended when quarterback Carson Palmer threw a bounce pass to running back Rashard Mendenhall on fourth down from the Cowboys 7.

Feely made 4 of 5 attempts but missed a 30-yard field goal and backup quarterback Drew Stanton had a pass intercepted on second down from the 12.

“To have (49) plays and nine points and miss a chip-shot field goal which is unacceptable also somebody’s accountable” Arians said. “It’s all about accountability. We’ll get it fixed.”

Palmer who completed 7 of 15 passes for 66 yards accepted more than his share of the blame using the word “sloppy” several times to describe the offense’s play in the red zone.

“There are some things we put on film that are really good” Palmer said “and there are some things we put on film that we need to talk about as a group.”

Palmer’s last three attempts were incomplete starting with the one to Mendenhall. On the next two he and receivers Larry Fitzgerald and Andre Roberts read the defense differently and no one was close to the passes.

“We want to be able to have a point for every minute we have in time of possession” said Fitzgerald. “Obviously we fell way short of that goal today.

“At the receiver position we haven’t done a good enough job of being crisp. And that falls on the players.”
