Let's just leave this as Chico said. This happens in every job. You give your notice and the next thing you know you are being shown the door by a security guy!There are always changes in new administrations due mostly to management philosophy and personality differences. It is never usually never about right or wrong.
The Prez has a pretty strong personality love or hate it, she is in charge.
I hope this has no baring on JL!
I would imagine that the new AD will evaluate Les and every other coach Bradley has. If they are seen to be the best fit for the job, then they stay. IMO I dont think there is anyone better for the job then Les, so I am not too worried. Unless the new AD decides that Les isn't "his guy" and wants to be in control of who is coaching BU's flagshipsport.
