Let's be honest. At this point, all three of the people being put up for the vote this week (Ben, Casey, and Frankie) will not, in the end, be supermodels. I voted for Ben last week, but after the derogatory comments he made (whether or not he thinks it's not what he meant... uh, dude, listen to the words coming out of your mouth) I'm not voting for any of them.
Meanwhile... Holly has been consistently great in photographs and her walk. Whether or not she wins, she's going to have a modeling career. Ronnie convinced the judges that he's more than catalogue... he'll probably have some sort of career (probably less on the catwalk than for, like, American Eagle, but work is work). Perry is strong in both categories, too. Shannon takes great pictures, but has been called too tall for runway (and her walk has been critiqued harshly) so she's less certain.
Will any of them be a "supermodel"? Doubt it.
But Holly, I think, comes out on top as far as a post-show career.
