The Oakland Raiders are winless through three games and Jon Gruden says Derek Carr may be trying too hard at times.

"I think, at times, he's trying too hard," Gruden said of his quarterback. "But we'll talk about that extensively here in the next couple hours. But I thought he played really good under some very tough circumstances.

"I think sometimes he needs to learn a little more patience and I think he will. But I'm really excited about the way that he has played and improved and mastered this offense. We're getting closer. That was a painful turnover. We will address that, and we'll make the corrections."

Carr threw a fourth-quarter interception in the end zone in Oakland's 28-20 loss to the Miami Dolphins on Sunday.
