The Arizona Cardinals offense put together a great season at 13-3 in 2015, but their offense was the big story. They led the NFL in yards. They were second in passing and eighth in rushing. They were second in scoring and tops in yards per play. Larry Fitzgerald set a career high and franchise record in receptions. Carson Palmer set a career highs and franchise records in passing yards and touchdown passes. His interception percentage was the second-lowest in team history, behind only his injury-shortened 2014.

That appears to be tough to do again in 2016, but that doesn’t phase Palmer. He expects progress ans improvement still.

“I expect to take another step,” he said on a conference call preparing for the American Century Championship golf tournament at Lake Tahoe he will participate in beginning July 22. “That’s why I’m training, working and grinding away to move forward and get a little bit better, here, there and everywhere.

“Offensively, I expect us to get better,” he said. “We finished in the top five in a number of categories and I expect us to move up a couple of rungs in each of those categories and continue to grow and develop. Keep trending upwards.”

One area where the Cardinals can improve is in their red zone efficiency. They were only 10th in red zone offense, scoring a touchdown only 60 percent of their trips inside the 20. They also were only 12th in third down conversions at home. They were tops at home, converting nearly half of their third downs, but that dropped to just over 40 percent at home. They were also ninth in short yardage offense.

It is going to tough to repeat what they did offensively, but Palmer has the right attitude. Prepare as if you want to improve offensively, even if there aren’t many areas to improve.

The passing offense perhaps will not be as high if the rushing attack increases. They were already the number one offense last year. They might be able to improve and move up in rankings in some of the individual offensive categories, but it’s going to be difficult to do much better than they already did.
