He certainly has a longer leash than most coaches, but there is some discontent among boosters starting to creep in. He is definitely a good recruiter, and a good coach in some respects, but is terrible at managing. At University of Richmond he was able to overcome this because he faced inferior competition and the organizational demands were less. This is based on what I have heard through UVA fans and a former player of his at UR.
I am certainly not trying to make this a race thing, but he has a lot of the shortcomings of Randy Shannon, who was a solid coordinator and recruiter, but not up to the HC challenge. To help manage this situation, the UVA athletic department essentially forced him to clean house and brought in experienced coordinators who could help address areas where London needs help. I expect he will have this season and next to see if the arrangement will work and then UVA will start talking to their deep pockets about a buyout.
