Arizona is expected to take an offensive lineman with the No. 7 overall pick, but Barkley might slip to the second round.
Barkley performed well overall at his pro day last week, with only five of his 60-plus passes hitting the ground. Several of his deep balls wobbled.
While there is optimism Palmer can spark the offense in Arizona, the Cardinals obviously are thinking ahead. Palmer is 33 and admits he's "only got a couple of shots left."
