Interestingly, Pastner was quoted a couple of times during the season as saying he told the team that he did not want to be calling plays for them. His ideal is to teach them a system, and then let them execute it without him having to yell out instructions on every possession. In that respect, I suspect it is very similar to what YIJacket was describing for KY and UNC.
My personal observation this year was that he did a lot less "sideline coaching" on offense than Coach Gregory did in the past.
I suspect that Tech's lack of individual athleticism this year means that most possessions required multiple passes and movement in order to create a good shot or drive opportunity. For KY and UNC, individuals able to utilize their athleticism to create scoring opportunities may make it look more like an uncoached offense, rather than a system, even when it is.
