He brought me into a new role and new industry. He had many strengths and some weaknesses. He had been with our company for 6 years. He grew market share by 10%, undisputed market leader by a healthy spread. Management has unrealistic targets and he was a scapegoat. He had been promoted twice in those 6 years. They created a new award 3 years ago to reward him and that caught on with the rest of the company (so now each division has one winner each year). We butted heads many times in a constructive way. I learned a lot from him. I'm torn because management is looking to me to replace and they felt that they would be able to let him go because I was capable of taking over (at least that's what I'm told). If it could happen to him, they can easily just do the same to me. Mostly, today I felt like Mark Antony in "I came to bury Caesar, not to praise him". TL/DR; boss who i viewed like a bigger brother got fired, execs look to me to replace him, but I've got a very bitter taste in my mouth how it all went down.
