Detroit ? If you can’t pass the Bettis family’s three-for-10 test, don’t bother trying to get on The Bus.

Jerome Bettis, the Pittsburgh Steeler running back who’s coming home to Detroit for his first Super Bowl, has devised a system for distributing his 15 tickets to the game. Only the family members and friends who attended at least three of his games for each of the last 10 seasons are eligible. Everyone else need not apply.

Already on the list are his parents, John and Gladys; his brother, John Jr.; and his sister, Kimberly.

“I’ve got three kids too, and I’m not sure what we’re going to do about them,” John Jr. said.

Jerome will arrive in town today with the Steelers, who are scheduled to land at 10 a.m. The Seattle Seahawks arrived Sunday afternoon.

Drawing such a hard line is difficult for the Bettises, among the NFL’s most agreeable, accommodating families. Likewise, because Jerome’s parents and siblings are happy to talk to reporters, Super Bowl week could be the busiest of their lives. To relieve some of the pressure on his parents, Bettis hired a New York public-relations firm to field their interview requests.

“I think it’s a testament to my parents,” his brother said. “We’re an open bunch. What you see is what you get. A lot of people don’t believe it until they meet us. It’s like, ‘Wow, you guys are nice.’ It’s not an act.

“We don’t know any other way. We don’t know the mean side.”

John Jr. was given the week off from his job as a loan officer because the media crush was consuming so much of his time. He has appeared on three Detroit morning shows, and has lost count of the number of reporters he has talked to.

“Everyone’s coming up to me,” he said. “I’m getting calls, the local paper sent a photographer out. So, as I’m selling loans and talking to clients, the young lady’s taking pictures of me.”

So far, none of the Bettises seem to be wearing thin on patience.

“We’re enjoying it,” John Jr. said. “It’s 13 years in the making. Yes, we’re tired. Yes, we’re doing a lot. But it only lasts for a short time, so enjoy the ride.”
