In his first year they had videos and statements about practice. I don't remember word for word, but CGC basically said that they don't have 'practice squads' and that all of the players ran all of the same plays as everyone else. In the videos they were running many-many plays with many squads all at a fast pace. He said that they were running far more plays per practice than anyone else because they wanted the second and third string players to have as many reps as the starters.
I do not know if they are still running practice that way, but I have read columnist reports about 'practice squad' guys, so that part of his statements was probably just marketing. Those videos and statements from CGC indicated that GT was practicing differently than any other football team. They also heavily gave the impression that the practice plays were fast pace and not much analysis was involved. Whether they actually ever ran practices the way the said they did or if they are running practices that way now is something that nobody on this board is likely to know for sure.
