Palmer, 34, doesn't deny that, but told Darren Urban of the team's official website on Tuesday that he'll understand if Arians and friends draft a young signal-caller in next month's draft.
"If you are in a position to draft the best player on your board ... and (a quarterback) is the best player on the board, you are not only making your team better by creating competition but you are helping out the future," Palmer said.
"I know I'm not going to play forever. It's hard for us players to admit that."
Palmer is coming off a season that saw him pass for a career-high 4,274 yards and more touchdowns (24) than he's tossed since 2009. On the flipside, the former Bengal and Raider absorbed an eye-popping 41 sacks, and his 22 picks were the most of his 10-year run in the pros.
"If I thought there was a guy that was in (Ben Roethlisberger's or Andrew Luck's) caliber, yes," said the coach, "but I don't think quarterbacks learn anything holding clipboards."
NFL Media's Daniel Jeremiah suspects otherwise, suggesting in his latest mock that Arizona will dial up Fresno State's Derek Carr if he's available with the 20th pick. We'll find out soon enough what Arians thinks of this year's collection of prospects.
