Cardinals coach Bruce Arians says his new quarterback, Carson Palmer, has played better football recently than most people think. Arians said in an interview on ESPN that he believes Palmer had an outstanding season in Oakland in 2012, and that people who focus on the Raiders’ 4-12 record need to realize that Palmer was not the one to blame. “What he did last year with the Raiders, in a crazy situation, I thought was very, very impressive,” Arians said. Arians didn’t elaborate on what he thought was crazy about the Raiders over the last two years, but suffice to say he’s not the only one who viewed the Raiders that way. And Arians makes a fair point: Palmer completed 61.1 percent of his passes, threw for 4,018 yards and had 22 touchdowns and 14 interceptions. Palmer wasn’t the reason the Raiders lost 12 games.
