There have been a number of posts on this and other boards about Shandi being edited to be the winner. I don't see that. How has she been edited to be the winner? The fact is she DOES have a runway model type body, and does look like a model.
As far as the girls being the same "types" as last season's, it might be fair to say that Shandi is being 'edited' to seem like Elyse, she clearly is the natural choice to be a top model, given her look and body type, but we have never heard her say anything about dreaming of being a model [in her audition tape she says "i want this so I can stop working at Walgreens"] and hasn't displayed any prior interest in fashion or the fashion industry. Yoanna is shown [as Adrienne was] as having always wanted to model, and as having a very thorough knowledge of various designers and the industry on the whole.
Mercedes is cute and sweet, and certainly pretty enough to model [as Shannon was] but doesn't seem to have a longstanding interest or attachment to being a model.
