Corolla seems to be one of those; he's ok with scripted material or when throwing in sardonic comments or observations, but I've never seen/heard the long-form compelling continuity and story-telling ability that's required for a show like Stern's (and Howard is one of the masters at it).
On Loveline, he's great playing off of Drew. Doing the sidekick thing to Kimmel on the Man Show, he was used to best advantage. As the lead on his new Comedy Central show, it's hit-and-miss, but remember most of his material is scripted. As the lead on the new radio show replacing Stern on the West Coast, I forsee problems...
