On Saturday afternoon, the large gathering at the Harper family draft party was getting a little uneasy.

Smooth, productive Fresno State receiver Josh Harper -- the youngest of former San Francisco 49ers Super Bowl-winning linebacker Willie Harper’s nine children -- surprisingly went undrafted. There were plenty of questions, but no answers.

Then telephone began to ring and the after-draft game was on. Teams were calling to try to secure Harper as a priority free agent. His older sister, Qiava Harper, didn’t say anything. She just sat and hoped.

Then it happened. Josh Harper, listed by ESPN draft analyst Todd McShay as the sixth best available undrafted free agent, agreed to terms with the Oakland Raiders, reuniting with his college quarterback, Derek Carr, who is entering his second season with the Raiders. Harper had 79 catches for 1,011 yards and 13 touchdowns at Fresno State in 2013 with Carr at the helm.

Qiava Harper gathered her thoughts, then went to her brother’s room to congratulate him and welcome him to her NFL family.

“Then I went out and cried a little,” said Harper, who is the vice president of premium seating and services for the Raiders.

Just like that, Harper will now be selling luxury boxes for people to see her brother try to score touchdowns. Harper played it straight during the entire process. She never talked to the team’s decision-makers about her brother before the draft and she didn’t try to sway her brother’s decision when he was on his own clock.

“My baby brother is joining the (Raider) Nation. I couldn’t be more proud,” Qiava Harper said. “I never mentioned anything. I was just being supportive. But I’m glad he made the right decision.”

Harper, who has another brother, Matthew, who is an assistant coach with the Philadelphia Eagles, was overwhelmed by all the well wishes and congratulations she received from co-workers when she showed up for work Monday.

One visitor stood out: Raiders Hall of Fame cornerback Willie Brown, who still works for the team. He visited Harper’s office to remind her that it doesn’t matter if a player is drafted or not, what matters is seizing the opportunity. Brown originally came into the league as an undrafted free agent with the Houston Oilers of the American Football League in 1963.

Qiava Harper enjoyed last year when the Raiders drafted Carr, her brother’s former teammate. It just got better.

“It must be God’s plan. We’re all here -- Derek, myself and now my brother,” Qiava Harper said. “It’s amazing.”

There also potential for in-office family bantering during the season. One of the ticket-office employees, Warren Verrett, is the older brother of Jason Verrett. He is a standout second-year cornerback with the AFC West rival San Diego Chargers, who conceivably could be covering Qiava’s baby brother twice a season for the next several years.
