Our offense was all world under Friedgen. We were consistently at the top or the top of the country with our offense. I think in 1998 we finished the season with the #1 offense.
When Friedgen departed, we had a better than average offense, but I remember our Bill O'Brien the OC going into the LSU bowlgame (first game without The Fridge) and after looking pretty solid first half, we looked like dogsh*t in the second half.
2001 followed and we did better than average as an offense with O'Leary and O'Brien as OC. We had definitely taken a step down from Fridge to OBrien, but O'Brien still had a respectable offense.
In 2002 OBrien was again above average. Gailey was at the helm, and he had some serious personnel issues at RB. Hollings who in my opinion WOULD have been the best RB in a single season for GT, got injured and we hit the wall offensively. OBrien was still ok, but apparetly he clashed greatly with Gailey.
2003 OBrien moved onto Duke and Gailey ran the helm for two years as Coach/OC. We started really sucking in my opinion. Had a decent running game, but our passing game was pedestrian at best. Its been much of the same the last few years.
Gailey is a ball control rushing pro offense. You don't see a lot of plays where we are spreading another team out. Friedgen was really in my opinion the guy who really started the Spread Option. But Friedgen was versatile, he liked to run all kinds of formations. He was big time into the triple option spread when Joe Hamilton was QB, and he liked a lot of play action as well. Watching his offense, you were definitely getting your money's worth.
O'Brien was a poor man's Friedgen (a very poor man might I add). We didn't run an option spread under OBrien all that often. OBrien though relied heavily on passes in the middle of the field in the seams, and we didn't have the talent to run much of that.
The best way I can put it is that Fridge's offense was like getting ready to light the biggest fire cracker in your bag. OBrien's offense was like lighting a roman candle. And Gailey's offense is like lighting a damp sparkler.
