No, Carson Daly was a guy who almost devoted his life to religion until he got his chance for success on MTV because he's got a pretty face and can read a prompter well.
Ryan Secrest has been in the entertainment business for a while - first as a popular radio DJ in SoCal, iirc, then gradually getting more popular and making it into mainstream and becoming the host of American Idol, now his own TV show. Not to mention he is actually kinda funny/witty, unlike Carson.
Have you ever watch Daly's show?!?! It's horrid!!! I'd rather put barbed wire through my nostrils and out my mouth and pretend that I'm flossing away at the bugers of my mind, rather than watch that POS show.
