Obviously a new coach chooses a staff, but I'm not sure how much say a coach has in exactly how much assistants get paid - ie money still is limited. So there might be an increased incentive for him to keep Gould and Thompson
if the money saved from not buying them out can go to additional pay to the other assistants.
Gould's contract appears to run through
April 2014 (actually it's worded so that he gets paid for one year beyond the current year if terminated, with the year starting ending in april) and Kenwick's through
February 2015. Clancy also has one through Spring 2014, but I'm not so sure a new HC would consider keeping him as much as Gould and Thompson who are definitely are better on the recruiting end and their position groups have always done well.
But we shouldn't keep them out of a sense of obligation to help them out by keeping them. They would easily get similar jobs elsewhere if they wanted because they are two well respected coached with excellent track records. Sometimes it's good to make a clean break to get rid of the old way of doing things, but at the same time, having a couple of coaches familiar with Cal the school and how things work would be helpful.
So that's just a long bunch of BS I wrote to say it's at the discretion of a new coach, which we all know anyway.
