Leno has provided reliably dull and pedestrian humor for the last 16 years, which is exactly what the suits and middle America love.
I don't find Kimmel all that funny, but watching him eat Jay alive on his own damn show was infinitely satisfying.
Conan will land on his feet, and Jay will have a broken Tonight Show and a lousy reputation amongst his peers. I guess as long as he gets to add a few more cars to his garage, that's all that matters.
