Turning serious for a moment, these are targets they could realistically look at and get if they got serious about the money and contract.
In no particular order...
Ed Orgeron has a chance since he is unemployed at the moment. He has SEC experience (albeit not a good record as a HC) and looked pretty decent as the fill in this year.
Tim DeRuyter has proven he can play in the big leagues for the most part. And his salary isn't exactly matching his on field performance right now.
Rod Carey is only in his first year at NIU and potentially could be a target. However, he hasn't been in that position for long and is playing with Doeren's players, so this could be a hit and miss hiring.
Rocky Long is another coach that doesn't have a good enough strength of schedule to move into the big leagues. But has proven himself to be a winner.
And as much as I hate to say it, Lane Kiffin could have the potential to go if the Alabama OC position falls through or a bidding war ensues. He would probably trade off his firstborn to get another shot at a HC position. However, for the moment is still slightly warm with the radioactivity from his last three programs. But Vandy might be willing to take a chance.
Matt Wells would be another coach that has potential to move up in the ranks. Utah State proved they could play ball and even their losses were reasonably close.
Vandy has to break out the checkbook to get in good talent. By and large, the program still has "Vanderbilt" in the name and frankly, a lot of coaches would be hesitant to move there considering the historical record of the school. However, Franklin has paved the road so to speak and the program might look a bit more appealing to some that want their shot at the big leagues in the SEC. A lot of non-AQ coaches (yes, I realize this doesn't matter any more) and potentially even AQ coordinators/assistant coaches might be willing to give it a go to get their name out there.
