The Cardinals called tight end Rob Housler’s number last week against the Panthers but he didn’t answer. Housler dropped one pass. He didn’t see another thrown ball because he and quarterback Carson Palmer had a miscommunication on a route. On another play Housler lined up wrong resulting in a penalty for an illegal formation. It was not a good Sunday for Housler who isn’t pleased with the way his season has gone. “I’m very disappointed in my production so far” Housler said. “It’s something you go out and just keep working on every day.” Housler missed the first two games of the season with an ankle sprain. He caught a pass in each or the next two games and none last week. Since Housler’s entered the lineup receiver Andre Roberts’ playing time has diminished. In the first two games he participated in an average of 73 percent of the plays. In the past three games Roberts has averaged about 55 percent. Roberts caught 11 passes in the first two games and only two since. The Cardinals have not compensated for the lost production. “He’s played more outside receiver with Robbie back” coach Bruce Arians said of Roberts “so that’s going to probably affect his numbers and is something we’ll look at it.” Don’t answer it’s HBO If HBO and the NFL come knocking Arians knows how he will answer. The NFL can now compel a team to appear on HBO's “Hard Knocks” as long as certain criteria are met. Arians said Tuesday night on SiriusXM that he would fight such an edict. He's not for it partly because the show sometimes features players getting cut and Arians thinks some of those conversations should remain private. Arians was asked again about “Hard Knocks” on Wednesday but deflected the question. “I have bigger fish to fry” he said. “We’re going to be in the playoffs so I don’t have to worry about it.” Playoff teams don’t have to appear on “Hard Knocks” the following season.
