The Biggest Loser - Ruined!

I have watched The Biggest Loser for many seasons now and have been really impressed by the weight loss people have achieved. This was mainly in part, aside from their own motivation, the two trainers Bob and Jillian. Before this season started, two new trainers were introduced, with Cara being trained to replace Jillian. At the season finale last night the show said good-bye to Jillian and introduced the new trainer - Anna Kournikova! Really!?!? You couldn't find anyone else? What happened to Cara? Aside from the "she lives in Florida and the show films in CA" issue... really?? There goes my interest in the show! How very disappointing!
