The plan is for Palmer to sit out of six organized team activities before throwing in the final three. He will also throw during the entire three-day minicamp, but even his participation in those sessions will be limited.
Palmer said he had thrown too much in the off-season for quite some time.
“I don’t think I’ve done a good job, probably, the last eight or nine years,” he said. “I’ve treated the last eight or nine years like I was 24, 25, 26. You’ve got to adapt, and it’s difficult for me to do.”
He said he had already thrown far fewer passes than he usually would have by now.
“March and April really is where I’m used to throwing and throwing and throwing,” Palmer said. Instead of piling up those repetitions, he is focusing on footwork and working out the muscles around his shoulder, he said. “You can still work without throwing the football,” he added.
While Palmer watches, Drew Stanton and Blaine Gabbert have worked with the No. 1 unit. Stanton has been the backup to Palmer since Arians became Arizona’s coach four seasons ago.
“Drew had a great day,” Arians said. “Blaine jumped in there and made a mistake or two, but he’s only been here a day. I’m really pleased with how the quarterback work has gone.”
Stanton, 33, remains firmly in the No. 2 role, with Gabbert behind him. The other two quarterbacks — Zac Dysert and the rookie Trevor Knight — worked out on a second practice field.
Gabbert, who signed a one-year contract with Arizona last week, has had a disappointing career since being drafted in the first round by Jacksonville in 2011. He has never run the same offense two years in a row.
In the locker room Tuesday, Gabbert quickly rattled off the names of the half-dozen offensive coordinators he has had. The frequent changes have added up to numerous offensive schemes to learn.
