With Sullivan nearing retirement, next AD will be chosen by next President
No major University that has a pending change in its President hires a new AD in the lame duck year of a President. That's a decision that will await the next President. Littlepage has not retired yet, though it apears he is near that point. He likely knows that the next President will make the decision and its remaining in place until then (and may even have been asked to do so by the Board of Rectors). CL has overall done a good job - what has hurt the program is the decline in revenue due to the misfortunes of football - get football attendance back up to 60,000+ per game and that helps everything.
