There is something to be said for preparation time against Paul Johnson's offense.
Since Johnson took over at Georgia Tech in 2008, the Yellow Jackets are 21-6 when teams have one week of practice or less to prepare. Compare that to a 5-8 record against FBS opponents that had more than a week to prepare. Of course, the games that stand out most in that losing record are the bowl games, in which the Jackets have gone 0-3 under Johnson.
This year, Coastal Division opponents Virginia and Virginia Tech both have bye weeks to prepare for Georgia Tech.
