Here is my take on these three jobs
LSU: Could attract some quality coaches who have success in the 800-1500m. They are looking for points in 800m, mile and the DMR at nationals. Don't expect big name XC person for this job as that's not the focus at LSU. DMR, 800, Mile is where you're going to make your money. Their top choice turned the job down a few weeks ago. I expect they'll have someone soon.
Florida: The last three coaches didn't last more than five years here so be careful what you ask for. They have put scholarship money into the women's distance program but it doesn't seem they historically put much money into the men's distance program. With all their national titles, why would this change. Expect them to hire an up and coming young coach. Only chance they'll get a "name" person is if that person doesn't have a job and needs one.
Auburn: My opinion the best job of the three. They have been better than LSU and UF overall in XC because they'll put more scholarship money into it. Also it is the one of the three schools that doesn't seem that have unrealistic expectations. Coach Spry had a solid year in track with his new 400m group so I don't see him going anywhere. So I say War-Damn-Eagle!
