GLENDALE, Ariz. -- Carson Palmer isn't used to having a coach around his age. He's certainly not used to having a coach younger than him, either.
So, a younger coach calling plays for him? Definitely out of the ordinary.
Cardinals quarterbacks coach Byron Leftwich, who's 18 days younger than the 37-year-old Palmer, will call the offensive plays, head coach Bruce Arians said on Wednesday. Having assistants call preseason games has become a ritual for Arians during the past few years, but this is the first time someone other than offensive coordinator Harold Goodwin will be in charge.
It'll be odd, Palmer said, since Leftwich was also part of the 2003 draft class. Palmer was selected first overall by Cincinnati. Leftwich went seventh to Jacksonville.
"It's even more odd that I'm older than he is, which I just found out the other day from Google," Palmer said. "But it is a little bit ... it's different, something I haven't experienced."
Palmer said an "argument" over who was older led to Palmer searching the Internet for Leftwich's age. Palmer was convinced that he was younger.
"I'm like, there's no way I'm older than him," Palmer said. "And then Google settled the bet."
The biggest difference with Leftwich calling the plays, Palmer said, is having a different voice coming through his headset. Otherwise, Leftwich's experience with Arians has been of assistance. Leftwich played under Arians while with the Steelers in 2008 and 2010, giving him an in-depth understanding of Arians' offensive scheme.
"I think Byron and B.A. see the game very similarly," Palmer said. "Byron doesn't have a ton of or much history calling plays. But just his knowledge of the offense, his knowledge of being the guy that is hearing it through his headset is going to serve him [well] and give him some experience.
"I'm looking forward to it. I think Byron has got a tremendous future -- calling plays, whatever it may be. I don't think we're going to have the same game plan, the same set of plays that we would enter a normal game with."
Leftwich took over the playcalling duties during practice on Tuesday and continued Wednesday. It was tough for Palmer to gauge how Leftwich was as a playcaller during Tuesday's practice, "but I think he's going to do a great job," he said.
