Other than Petersen, Gruden, Kelly, Patterson, Shaw, and other obvious longshots like Swinney... who do you got in your top 3?
If history is any kind of a teacher, Gruden, Kelly, Bob Stoops, Patterson, and Peterson are totally unrealistic choices. With that being said, for what I know, the top 3 realistic choices would be:
1. Brohm
2. Venables
3. Babers or Strong
