Ohhh, the good ole days. Not sure the actual list of coaches, but the criteria seemed to be success of program, strength of schedule, etc..... I know the AAA vote is confidential, maybe you can ask who is on the list. I don't care to say I am. I remember back in the day, the trouble G had actually getting coaches to vote. Most don't want to even take the time. I know I spend a lot of time looking up scores and trying to find articles before voting. Not a perfect system, but it does lead to discussion.
For the record, if I voted in AA/A I would have ND #1 each week to try and get back in cannon's good graces. =) and aggravate G. =P
