Anyone with any inside information, Did Skip Bertman do all that he could do to

Not trying to come here and start any type of controversy and I understand some will ask, "you come to the Tiger Rant and ask this foolish question". However, I know that some on here that post work at LSU and inside the Athletic Dept, etc. so do you know, Did Skip Bertman do all that he could have done to keep Nick Saban? Certainly, I know that 's all water under the bridge and what could have been is not the way it turned out? If you know and truly are an insider, Was Saban just Hell bent on going to the NFL or Did Bertman's ego stand in the way of Saban's ego. Just asking, don't need to be lectured by anyone , but its just amazing of how we had really closed the gap on Bama and it has once again really seemed to have widened as Hanagriff and Risher said on Saturday's post game show. Just curious if anyone really knows. TIA
