"It sucks whenever your team is competing and you're not," McCaffrey told reporters, per the team's website. "But you've got to follow the system, and I'm glad to be here now."
According to the Panthers' site, McCaffrey was thrown right into the fire, working out on kick coverage, participating as the fifth option in running back drills and even running plays out of the wildcat. The eighth overall pick said he was comfortable playing all over the field.
According to the story, Carolina's first-round pick had been restricted by an arcane rule from participating in organized team activities and the first two days of minicamp until his school year at Stanford, which operates on the quarter system, had ended. One day after the conclusion of classes Wednesday, McCaffrey made his debut.
