Personally, it's because of her behavior and entitlement last year (which has been somewhat toned down this year so far, at least on what was shown) among other things. She couldn't control the nepotism and favoritism shown by Kelli, but Victoria's own immature behavior made her seem younger than she was. In addition, her dancing is out of control (to me), she gained 11 pounds last year, lied about certain things and did so straight to Kelli's face, and other things. I will give her that she's so far seemed to keep her weight in check this year, but I don't see that her dancing, especially her turns, have improved. I could say SO much more, but won't. At least not right now.
Wasn't there the thought last year that Kelli was petitioning Charlotte to make the team 40 girls so she WOULDN'T have to cut people she wants on the squad? Unless every other rookie candidate is far better than Victoria and Kelli can't stomach the thought of cutting her again, then I don't see the problem of who the last cut should be. We already know that Kelli ranks the girls as to who's the top 36 and who isn't so unless one of those girls is SO close and Kelli's just giving her time to see if she can get there. . . .Still, if that's the case, the girl has had all summer to get there and just can't seem to make it, then just cut her and move on to the squad so the girl can rest, recover, and actually have a bit of a break before she decides what to do next.
