Perhaps cause they were the best fit?
You want a a polished presenter who can moderate and guide the chat.
A Pitt, Bracey, Ginnane, Sampson type rather than a Brandy, Cronk, Ennis who offer great insight but haven't done that anchor role.
For mine I would have gone Pitt with Ginnane as my second pick
Out of the choice's of the girls, agree Pitt is miles ahead of Vonnie.
Then again, Kerry Ann Kennerly would be better than Vonnie
