Shaw was Harbaugh's OC at San Diego before joining Jim at his alma mater Stanford. He was the OC for every year Harbaugh was at Stanford, taking over as HC in 2011 when Jim went to San Francisco.
He went 96-54 including three Pac-12 Championships. After only winning 14 games in the last 4 seasons he has stepped down.
Shaw was the architect of Harbaugh's offense at Stanford, and we see a lot of Shaw's scheme in Michigan's offense today. Power run with a pulling guard. 10 personnel with 3 TEs. Levels route concepts for easy short crossing passes. Shaw is essentially a child of the west coast offense, playing under Bill Walsh and Dennis Green, and coaching with Brian Billick.
I have no idea what Shaw wants to do with his future. I have no idea what if any changes could come to the Michigan coaching staff this season, but if there weren't any it would be the first time. Would Shaw consider coming to Michigan? As an analyst, would it have to be OC, and would he even want that? He was just a head coach for 12 seasons. Does he even want to coach anymore?
I am not suggesting there is anything on the horizon to think Shaw would come to Michigan in any capacity, but it would make a ton of sense depending on what each sides wants, the role, etc.
