Warning from the PR people would have been nice to help avoid the girls running over the reporters, but that's about the extent of what difference it would have made. I have a feeling stuff goes on all the time on the field during pre-game, but maybe just not during the first pre-season game. At the end of it, the DCC is a small cog in a large machine and just has to work around distractions.
As for keeping Simone and Kat - I'm wondering if they were kept because they were worried 32 would have been too few since clearly injuries do take down girls (and probably more often than we necessarily see). Agree though that unless they improve significantly during the season or turn out to be huge hits on appearances, that they'll be one and done vets.
