I agree GB. Although taking over from Conan wouldn't be easy.
He is a cool enough dude and was funny at times at SNL but he's just too nice, gets really nervous like you said and the show is just tame and boring as a result.
Maybe once he gets the hang of it he will come out of his shell more (it would be one of the hardest gigs in TV and guys like Leno, Letterman, Conan etc have all done thousands and thousands of shows over decades) so I won't be too harsh on him just yet but yeah I agree, it isn't looking good at the moment.
