NAPA, Calif. -- What was the first question Oakland Raiders rookie quarterback Derek Carr had for veterans as time grew short to report for training camp?

“Where do I park when I get there?” Carr sheepishly admitted.

Carr, the Raiders’ second-round draft pick out of Fresno State and QB of the future, found the Napa Valley Marriott Hotel & Spa’s players-only lot on Wednesday -- yes, he drove himself rather than ride the “rookie” bus from Alameda -- and, just like that, his future was kickstarted.

“I’m starting to learn how to be an NFL quarterback,” Carr told a cluster of reporters after checking in. “But I’ve still got a long way to go. So I’m just going to rely on my coaches and the team to help me get through my first camp.”

Carr has first-hand experience, so to speak, what with older brother David spending 11 years in the NFL after the Houston Texans made him the No. 1 overall pick in 2002.

In minicamp, Carr was elevated to second-string on Oakland’s depth chart, ahead of Matt McGloin and behind new starter Matt Schaub.

Ironically, it was Schaub who replaced the elder Carr in Houston and, if all goes according to plan in Oakland, the younger Carr will replace Schaub in the near future.

Schaub has been an accommodating mentor.

“Hopefully, Matt doesn’t get too annoyed at me for asking too many questions,” Carr said with a laugh. “Because I’m going to ask even more now. I’m going to try and pick his brain as much as I can.”
