While I am not fan of the VK edit I can not blame Charlotte, Kelli et al. for wanting women like VK, Dayton, or Cassie on the team.
They were raised in the Cowboys life, they get the brand, the understand what it means, and respect it. They are a far better gamble than dancers like Kalyssa or Erica is the long run. Protecting the brand is second nature and family tradition. Keeping it close to home just makes good business sense.
That said, its not VKs time. She seems to lack a bit of refinement that most 18 year olds really shouldn't have anyway. A little taste of failure at this age is great for growth.
...also her teeth bug me :)
