It was around this time a year ago when Mike Abercrombie began experiencing one of his Seahawk moments.

The Seattle Seahawks were losing at home to the Dallas Cowboys and, in Section 331 at CenturyLink Field, Abercrombie began going through his mental checklist.

Suddenly, a light bulb came on. Abercrombie remembered that he hadn’t raised the No. 12 flag back home in Oak Harbor, a staple during Seahawks game days. His wife Amy, who was sitting next to him, remembered how much that bothered him.

“You’re about as bad as Patrick,” she said, referring to their eldest son, another diehard Seahawks fan. “We were losing and you wanted me to call the neighbor back home and have her come to our house and put up the flag.”

Seahawk superstitions run deep in the Abercrombie family and they’ll be on display again when the couple attends Seattle’s next game against the Detroit Lions on Monday Night Football.

Aside from the standard Seahawks jerseys, socks, shoes and necklaces that are game day essentials, the couple is certain the team will be doomed if Mike doesn’t don his green rally hair under his cap.

He also owns a foam hat in the form of a Seahawk that is retired during the regular season.

“He says it’s bad luck,” Amy said. “He will not wear it.”

“Not during the football season,” Mike said. “I’ll wear it preseason or postseason.”

Quirky superstitions are part of the fabric of being a sports fan, and the Seahawks’ “12’s” are not exempt.

Usually, fabric is involved whether it’s wearing the same shirt, often unwashed, or socks.

At least, that’s how Rick Castellano sees it.

On game days, the executive director of the Island County Museum likes to wear the same long-sleeve Seahawk fan shirt, with a short sleeve Steve Largent jersey over it, as well as his Super Bowl XLVIII hat.

“Our toy poodle wears a fan jersey on gameday,” Castellano said. “If the Hawks are having a bad day, a layer may be removed …

“Also, I make sure never  to wear any opposing team colors on game day ­­— including undergarments. In other words, just common sense stuff.”

It all makes sense to Michelle Curry.

Curry, vice president of the Whidbey Island Sea Hawkers Booster Club and a loan officer at Peoples Bank in Oak Harbor, said superstitious rituals can give fans the feeling that they’re helping the team win.

She recalled the desperate times during the NFC Championship game last season when the Seahawks trailed the Green Bay Packers 16-0 only to rally and reach the Super Bowl for the second consecutive season.

She was watching the game on television with a friend, Charles Aldana, when the Seahawks appeared doomed.

“Charles and I had tried all of our normal superstitious routines. Nothing was working,” Curry said.

She said Aldana wound up in isolation in the bathroom, listening to the game on the radio while sitting in a bathtub, begging for the Seahawks to rally.

“I ended up in the kitchen, unable to watch the game, red oven mitts on both hands and head on the counter,” Curry said. “Till this day, I still haven’t seen the second half of that game, but we won and we celebrated.”

Oak Harbor Mayor Scott Dudley is a big fan of the Seahawks, having attended the past two Super Bowls, but doesn’t consider himself overly superstitious.

He still makes sure to wear Seahawks colors during Blue Fridays. After all, he’s expecting big things this season, despite the team’s 1-2 start.

“We’re excited, not only about Monday night, we still are making plans for San Francisco (site of this season’s Super Bowl) come February.”

As fanatical as Mike and Amy Abercrombie are, they’ve got nothing on their oldest son.

Patrick Abercrombie’s room is a Seahawks shrine decked out in posters, mini-helmets and an overflow of other trinkets. Patrick’s superstitions are reflected in the change that spills from a Seahawk piggy bank.

“I’m not allowed to touch his money,” his mom said. “You can’t move it.”

A bit of a family feud has developed over the Lions game.

Mike and Amy Abercrombie, who own two season tickets, will be attending the Monday night game while Patrick, in his second year at Western Washington University, will be watching from afar.

If that wasn’t bad enough for Patrick, things got worse when his parents won pre-game sideline passes for that game during a drawing at a Whidbey Island Sea Hawkers Booster Club meeting early last month.

Amy Abercrombie remembers receiving a text from her son with some angry faces.

“He’s not happy that I’m going Monday and he’s not,” she said.

“He said, ‘I wanted to go to that game from the beginning and now you’ve got field passes?’” Mike Abercrombie said.

The Abercrombies are among 108 members of the second-year club, which is an associate satellite chapter of the parent Sea Hawkers Booster Club.

The group meets regularly at Flyers Restaurant and sometimes gets together to watch games. A third Deception Pass bridge rally is being planned for the coming months.

The timing of the Abercrombies deciding to buy season tickets couldn’t have been better, but it didn’t seem that way from the start.

They got their tickets at the start of the 2012 season, the year Russell Wilson emerged as the starting quarterback.

“I was thinking the whole time that Matt Flynn was going to be our quarterback, then Russell Wilson takes over,” Mike Abercrombie said. “I was thinking, ‘What have we gotten ourselves into?’”

Two Super Bowl appearances later, the Abercrombies are happy with their choice, though with two sons, tough decisions have to be made before game day.

This time, the parents won out, prompting dad to do a little good-natured teasing with oldest son.

“I told him, I was going to invite Marshawn and Russell over for Thanksgiving,” he said.
