The 2014 defense is only the 43rd best scoring defense in the country but has the 17th best scoring offense backing it up. In contrast, 2005 didn't win anything of note with a 17th ranked defense supported by the 104th best scoring offense. If the opponent wasn't a hapless team from the Triangle, then Tech didn't do much in 2005 but holy crap the defense still made opposing offenses squirm.
Back to turnovers, Tech is 12th nationally in turnovers forced and 7th best in the nation in interceptions garnered. In the first 5 games, Tech never gave up more turnovers than its opponents and averaged +1 turnover margin per game. In the Duke and UNC debacles, Tech had a -1.5 turnover margin. After the two game skid, Tech has averaged +1.8 turnover margin per game. Tech only gets about 10 drives per game and through poor turnover margin, we really shot ourselves in the foot against Duke in particular.
FSU will be the 39th best rated passer in the nation (fourth best Tech has faced). FSU is ranked 124th in interceptions thrown at 19 interceptions thrown on the season. Florida State is 94th best in the nation in turnover margin at -0.33 per game. I think Tech should expect to force some turnovers from the mistake prone Seminoles.
