When the final whistle blew on Friday's rookie minicamp practice, most players were ready to call it a day. But for undrafted free agent quarterback Haynes King, the work was just beginning.

Determined to master the Carolina Panthers' playbook, King took matters—and his teammates—into his own hands. He organized an impromptu practice session in the most unlikely of venues: a parking lot near Bank of America Stadium.

"It was kind of like a knock on the door, trying to find people," King said after Saturday's practice, which wrapped up the two-day camp.

The Georgia Tech product recruited fellow rookies, including former Memphis QB Brendon Lewis, to join him for extra reps. His efforts paid off as he assembled a full offensive line, a tight end, and three wide receivers—among them third-round draft pick Chris Brazzell II.

The group found a nearly deserted parking lot near their hotel, using the concrete space to run through plays that had given them trouble earlier in the day. For King, it was about building chemistry and sharpening execution before Saturday's session.

"We had a couple of hard ones and wanted to be able to communicate and operate at a high level when we went out there," King explained. "Making sure you're going on the right tracks."

That leadership hasn't gone unnoticed. Brazzell praised King's initiative, noting, "He's in the locker room, helped me go over plays, talking the plays out for me. He's a good leader. A lot of people want to be great, so he decided, 'Man, we go to the parking lot.'"

In a league where every edge counts, King's parking lot classroom might just be the foundation of something special in Carolina. For fans and aspiring athletes alike, it's a reminder that greatness isn't just built on the field—it's built wherever you're willing to put in the work.
