The “social butterfly” was in the perfect position.

Georgia Tech had the ball on its own 36-yard line with 70 seconds left. Florida State led by five. A touchdown would give the Yellow Jackets the lead.

That dream was dashed after Karlos Williams stepped in front of a Yellow Jackets receiver running a crossing pattern. He tipped Tevin Washington’s pass in the air with his right hand, snatched it and sprinted 40 yards down the left sideline.

Teammates mobbed him outside the end zone. The defense celebrated with a dog pile.

With one minute remaining, Florida State players and coaches knew they would win the ACC championship and play in the Orange Bowl.

Karlos, the younger brother of Vince, a starting linebacker for the Seminoles, contributed to special teams this season, but did not start for the Seminoles defense. However, an injury to linebacker Nick Moody on the game’s opening kickoff allowed the younger Williams extended playing time.

He certainly took advantage. Along with his first career interception, Williams’ notched 11 tackles in the Seminoles win. He had only 20 tackles this season coming into the championship game.

“Coach Jimbo always talks about you can’t drive a car looking in the rear-view mirror, because you end up crashing,” Karlos said after the game. “Thinking about [defensive coordinator Mark] Stoops. I’m very happy for him going to Kentucky. Tank, I’m very proud of him; he played a great season [after] losing B Jenks early in the season, but as far as that, we kept looking [out] the coach always talks about, and we’re home safe now going to Miami to play in the Orange Bowl.”

The player coach Jimbo Fisher called a “social butterfly” a few weeks ago played the best game of his collegiate career on the ACC’s biggest stage. Karlos, a gregarious sophomore, is the polar opposite from his brother, Vince.

“Karlos, he’s played great all year, did special teams, whatever you asked with the ball in his hands and he gets — he’s very instinctive, he’s a very good football player, he’s physical and got good ball skills and he played a tremendous game.” Fisher said. “The guy is going to be a great player. He’s got two years left, and I’m glad of that.”

But the Williams brothers do have at least one thing in common: they both contribute to an elite defensive unit. Vince and Karlos will don FSU jerseys together for the last time on the first day of 2013 at Sun Life Stadium in Miami.

Complete Conference Standings

Boston College (2-10, 1-7 ACC)

Bates has been tweeting information about the coaching search and recently wrote that he is “Very excited about the level of interest in our football coaching job and the quality of the candidates.” Plenty of NFL assistants are rumored to have interest in the job and Bates could try the professional ranks for a new coach.

• Wide receiver Alex Amidon and linebacker Nick Clancy were among five Eagles to earn ACC honors last week. Amidon and Clancy were voted onto the first-team. Tackle Emmett Cleary made the second-team and punter Gerald Levano and linebacker Kevin Pierre-Louis were honorable mentions.

No. 15 Clemson (10-2, 7-1 ACC)
• Tajh Boyd was tabbed the ACC’s player of the year and offensive player of the year last week. He beat out North Carolina running back Giovani Bernard by one vote in both tallies.

Miami (Fla.) (7-5, 5-3 ACC)

Football is about effort. We need to make some changes to get better.”
