Here is a good article that I think sums up the position of all of these AD's that have been put in question for their participation in the Fiesta Frolic.

It is important for AD's like Dave Heeke to be at "convention-like" events such as these because how else is he going to land scheduling with teams like N.C. State and a future Big XII opponent. Just some more food for thought.
