you're right that it was no secret. i was aware of it being on your boards and having GT friends. i'm not sure how much each head coach keeps tabs on what other teams are doing in their open practices. makes sense to do so, of course, but i'm sure there's a cost-benefit analysis there somewhere.
i agree with you that GT gains a lot from having run it against dook.
i'm actually excited about what the diamond brings to UNC. we have three legit RBs that get equal playing time. we also have two ABs who also get plenty of playing time. so, each of the three backs in the formation can be a legit threat. and if we have marquise williams at QB, then all four can be (as runners). we also have four receivers 6'4" or taller who could take advantage of one-on-one jump balls. we also have two burners who are faster than most DBs.
i'm sure UNC learned from having run it against MTSU. now, will UNC use it against GT? who knows. but GT has game tape on us, too.
