I've always said that about Season 7 - they took more on the squad fully expecting that Cassie (and maybe others) would not be able to dance. Yes, not a great look to fire someone just because of an injury, but I object to Cassie being given so many opportunities that year when she couldn't keep up her end of the bargain. No way she should have been given group leader, show group, etc. when she was having to "electively pull herself" from pregame performances. She most definitely took someone's else's spot, especially when talking about the opportunities of show group. No other cheerleader (save VK) would be given such special treatment.
Sorry for getting a bit off-topic as I realize this section is about the current squad.
