Bruce Arians is either very confident in Carson Palmer‘s health, or trying very hard to convince himself his team was smart not to draft a quarterback.

The Arizona Cardinals head coach had plenty to say about his star running back, his team’s 2016 turning point, and his history of drinking paint in a string of media appearances Wednesday, but couldn’t avoid talk of his aging quarterback.

Though the 37-year-old Palmer reportedly contemplated retirement this winter, Arians says he looks as good as ever after OTAs, and has plenty of games left in him.

“He can play easily until he’s 42 if he wants to,” Arians said on CBS Sports Radio’s “Tiki and Tierney” on Wednesday. “He is hungry as hell right now. I wouldn’t let him go in OTAs. It was like taking candy away from a kid.”

Palmer has been Arians’ starting quarterback for the past four seasons, and had a career year in 2015, throwing for 4,671 yards and 35 touchdowns. While discussing differences between all the quarterbacks Arians has worked with – including Andrew Luck, Peyton Manning, and Ben Roethlisberger – he said Palmer is the best deep passer of them all.

“I’m really lucky to be around these guys. Each one is so unique,” said Arians, whose book, “The Quarterback Whisperer: How to Build an Elite NFL Quarterback,” was recently released. “I’ve never seen anybody throw a deep ball like Carson.”
