After the Las Vegas Raiders wrapped up their joint practice with the San Francisco 49ers on Thursday, a Raiders beat writer noted the standout performances of two of the team's rookies.

Crosby, who relished an opportunity to practice against another team, routinely made his presence known in the backfield. 49ers quarterback Brock Purdy was consistently flushed from the pocket. The 49ers offensive line simply couldn't block Crosby. Crosby was thrilled with how the practice session played out.

There were several rivalries renewed Thursday at the Raiders joint practice with the 49ers. Including several players, coaches, and the team itself.
