Georgia Tech's biggest problems over the past three years has not really been the option offense but the porous defense.
Johnson thought he had solved the problem by bringing in former Virginia coach Al Groh to run the defense after he was canned. Instead, the Yellow Jackets never really took to the 3-4 and had trouble taking offenses off of the field.
Not since 2008 has Georgia Tech's scoring defense been better than 64th in the country.
Groh was canned in the middle of the season last year and another former ACC head coach, Ted Roof, was asked to try to fix the million-dollar problem with the Yellow Jackets.
Roof, the former Duke coach, has a pretty horrible record as head coach at 6-45, but his work as a defensive coordinator is better.
Last year at Penn State, Roof maintained a difficult situation following the Jerry Sandusky fallout and still produced a defense ranked in the top 25 in nearly every statistical category.
He was also the coordinator for Auburn's BCS championship but followed that up with one of the worst defenses ever the following season.
To help Roof is former assistant Mike Pelton on the defensive line, a key to Georgia Tech's woes over the years.
If Pelton can produce and help ease the transition to a 4-3, Georgia Tech might finally be able to make some noise in 2013.
