BLACKSBURG, Va. — When Scot Loeffler stepped into Lane Stadium for the first time since leaving Virginia Tech to join close friend Steve Addazio as Boston College’s offensive coordinator, it wasn’t just the surroundings that were familiar.

Looking across the field, he saw a Hokies defense he spent three years scheming against as Tech’s offensive coordinator. Loeffler had three years’ worth of chess matches with Hokies defensive coordinator Bud Foster in practice.

“Coach Foster and their offensive coordinator, Scot Loeffler, played against each other for many years here,’’ said Virginia Tech’s first-year coach, Justin Fuente. “There is some familiarity there but there is every week after watching video and those types of things.

“Not every week you play your team’s old offensive coordinator. I would say those two coordinators are familiar with each other and their personnel.’’

In Virginia Tech’s 49-0 rout Saturday, it seemed as if Foster saw Loeffler’s every move coming. The Hokies held the Eagles to just 124 total yards. BC quarterback Patrick Towles completed just 9 of 28 passes for 80 yards. When he tried to take a shot downfield to his newfound deep threat, Jeff Smith, Hokies cornerback Adonis Alexander had it played perfectly for the interception.

The Eagles’ rushing attack didn’t fare much better. Michael Walker had the ball popped from his arms on his first carry of the day, and the fumble set up Tech’s first score. Jon Hilliman was bottled up for just 2 yards on 10 carries. He was one of seven rushers who combined for 44 yards.

“We obviously have the utmost respect for BC and how physical they play,’’ Foster said. “I thought that was going to be the big key either way, how we control the ball offensively up front and how we control the line of scrimmage defensively.’’

Shutting out his former colleague was a point of pride for Foster.

“Shutouts are hard to come by,’’ he said. “I don’t care who you’re playing against. That’s something we’re really, really proud of for our kids and happy for our kids.’’

Addazio hired Loeffler in the offseason to improve an offense that was woeful a year ago. They cut their teeth together under Urban Meyer at Florida and Loeffler served as Addazio’s quarterbacks coach at Temple.

“Scot is really one of the better quarterback coaches in the country,’’ Addazio said. “I know Scot really well. He’s a good friend, but most importantly, he’s a hell of a football coach and a good mind, and I wanted to make sure that we developed at the quarterback position, and I wanted to make sure we developed in the throw game, and I knew Scot could bring that to us.

“So when he became available, I knew I wanted to get him on my staff, and he’s done a great job. So I’m real happy with what he’s brought to the table but not surprised.’’

But Addazio had also faced Foster enough times to know the kind of a challenge his defense would present.

“I think Bud Foster is a heck of a defensive coordinator,’’ Addazio said. “I have, in various different capacities with different programs, gone against him a lot of years, and those defenses come to play, and he does a great job of defending your formations and your plays.’’

Points are neededThe Eagles dropped to 2-11 under Addazio in games in which they allowed 17 or more points . . . Back when he was at Temple, Addazio had his eyes on Tech running back Sam Rogers, but never made him a scholarship offer. Rogers popped on his radar again in the third quarter when he caught a 4-yard touchdown pass that put Tech up, 35-0. Seeing the player Rogers has turned into at Tech made him wish he had. “We didn’t offer him. We should have!’’ Addazio said. “He played that fullback position at that time. That’s what we saw him as. Are you playing with a traditional fullback offensively? So they become limited opportunities for those guys sometimes. But he’s gone on and just really been a dominant player; became a scholarship player there. He’s just really good.’’ . . . The Hokies inducted six players into their Hall of Fame, including Redskins defensive back D’Angelo Hall and former Lions running back Kevin Jones . . . The Eagles are 5-9 against Tech since joining the ACC and 4-7 in Blacksburg.
