Ian Johnson knows how to keep the Boise State and WAC compliance officers busy.

In 2006, the star tailback's crochet business prompted questions about NCAA regulations prohibiting athletes from using their name or likeness to promote or sell commercial goods. The NCAA shut him down.

Now it's his wedding that is under scrutiny.

Not only is Johnson barred from accepting free services or discounted pricing not available to the general public, but his fiancée, BSU cheerleader Chrissy Popadics, and her family fall under the rules, too.

BSU compliance director Matt Billings and the Bronco coaches have tried to educate everyone involved.

"Ultimately," Billings said, "the person has to make the right decision to protect the program."

Johnson, a Heisman Trophy candidate entering his junior season, became a national celebrity Jan. 1 when he scored the game-winning two-point conversion in the Fiesta Bowl and promptly proposed to Popadics on national TV.

They will be married July 28 in Boise.

Marriages are not uncommon on the Boise State football team, but most go completely unnoticed by fans.

This one, however, is big news — and Johnson's popularity could turn the wedding into a circus.

That's where offers of inappropriate gifts or other perks could become a problem.

Johnson, though, says not to worry.

"I'm well-informed," he said. "Chrissy is well-informed. Her parents are well-informed. So it's not one of those things that's going to be a problem."

Here are a few of the rules that pertain to the wedding:

• No freebies: Johnson, as a student-athlete, can't take any extra benefits. Most people know that.

But Popadics and her family fall under a friends and relatives portion of the rule. They cannot accept anything that Johnson can't.

It would be the same as an agent giving a star player's best friend $10,000, with the clear understanding that the money would end up with the star player.

BSU staff members have met with Johnson, Popadics and both sets of parents to discuss the rules.

"Her parents are starting to get into the loop," Billings said. "All of a sudden they're thrust into things."

Popadics and her family say they understand the scrutiny they all are under, and are being careful to make sure they abide by the rules.

• WEDDING GIFTS: Coaches can give gifts. BSU coaches are allowed to give Johnson a wedding gift, but only if they do the same for all of their players who invite them to weddings. The same rule applies to staff members. They must be able to document that under similar circumstances they have given gifts in the past.

• BOOSTERS: Boosters should not give gifts. The general rule of thumb for gift-giving is to follow your standard practice. If you usually give a $50 gift to an acquaintance who gets married, then that's what you should do for the student-athlete in your life.

However, WAC assistant commissioner for compliance Anthony Archbald says boosters should not give gifts at all.

"It's just a very, very fine line," Archbald said.

And like any fine line, there are exceptions. People who had a relationship with Johnson before he became associated with the Broncos can bring a gift. And a booster who also is his boss — Johnson works for DeBest Plumbing, a Bronco supporter — can give a gift under the same guidelines as a coach.

The problem with allowing boosters to bring gifts is that a popular athlete could invite every season-ticket holder to the wedding and collect tens of thousands of dollars worth of cash and merchandise.

That has not been an issue with Johnson.

"Basically the premise is no special arrangement is being made for Mr. Johnson as a student-athlete," Archbald said.
