New Arizona Cardinals quarterback Josh Rosen already knows what jersey he will wear in Arizona. He will wear the number he donned in college at UCLA — No. 3.

Cardinals fans don’t have to think long to remember who the last to wear that number was. It was Carson Palmer, who retired after five seasons starting at quarterback.

Rosen knows whose footsteps he follows and actually was a Carson Palmer fan growing up.

“I looked up to Carson when he was playing for the Bengals,” he said in his introductory press conference. “He and Chad Johnson, or Ochocinco, were two of my favorite players. It’s an honor to wear his jersey, and hopefully, I can do him proud.”

Cardinals fans have some very good memories of Palmer wearing No. 3. He set team records and led them to the most successful five-year run in franchise history.

Rosen has some big shoes to fill.
