A year ago, quarterback Carson Palmer's brain was crammed with a dizzying array of details of the offense of his new team, the Arizona Cardinals.

Needless to say, the adjustment took some time.

When Palmer finished his first OTA (organized team activity) session of his second season on Tuesday, he said there is "zero comparison" between the way he feels now and the way he did a year ago.

Then, he faced learning new concepts, new plays, new terminology and a new philosophy from first-year coach Bruce Arians.

Now, he says, that frustration has been replaced by comfort and confidence.

Arians says that last year, Palmer was learning. This year, he's coaching.

The OTAs continue through Thursday at the team's' practice facility in Tempe.
