I wouldn't say I feel sorry for Conan. Not at all.
I just think that all of us, in our careers, have something we strive for and/or idolize.
He obviously had a lot of respect for the legacy of the Tonight Show. He dug being the host. He would have liked to have stayed on and made it successful.
I think anyone would be disappointed if something they really wanted to do well was taken away from them before they had a real chance to make it work.
