Guys like him are not really an asset, anyway, long-term .... they inevitably do a "Dave Garroway" and embarrass whoever (producers, sponsors, etc.) was backing, sponsoring, mentoring them, etc.
Eons ago, before the last Ice Age and even before "America's girl friend" Jane Pauley, Dave Garroway had the Today show on NBC. (In the mid-50's.) He got arrogant and high-handed, and one day he actually fired his music guy, Julius De La Rosa, on-air. That was the end of Garroway, too. The public turned him off, and soon NBC did, too.
They come and they go. You may remember others.
For "Dave Garroway" in my post above, pls substitute "Arthur Godfrey", another early, early-morning host.
The point, for posters about Bill O'Reilly, is the same.
