I am not sure what you are referring to GTT.
If you mean, do I prefer to give Spencer a chance before bringing Roof back, I would say yes. I would also go along with Gailey if he decided to bring Roof back, but that would not be my first choice.
I have never been an opponent of Roof. Each time I brought Roof's name up, I always stated I thought he was hamstrung by O'Leary. However, I did say he was ultimately responsible because he could have bucked O'Leary.
I also stated, I thought the Duke move would be good for Roof and give him a chance to prove his worth on his own without O'Leary. I was a Roof fan, but not an O'Leary fan.
To be honest, I doubt Gailey would bring Roof back as DC. If he thought Roof would have been the right person as DC under him, he would have kept him the first time as DC.
If O'Brien is gone after this year, the staff would be purged for all practical purposes. I doubt Gailey would consider rebuilding the same situation on the defensive side of the ball.
Just my guess.
