Cardinals look to improve pass blocking in camp's final week
And there were issues in that area in last weekend's 22-19 preseason loss to San Diego.
Palmer, a 35-year-old quarterback coming off ACL surgery, played less than a quarter and was sacked twice. Backup Drew Stanton was sacked four times. All six sacks occurred in the first half.
Coach Bruce Arians, speaking as the final week of training camp got under way, said the problems were a combination of getting beat physically and making mental errors.
General manager Steve Keim, in his weekly radio appearance, said the Cardinals can have an explosive offense but Palmer has to be given time to pass the ball.
