PWtorch.com is reporting that Isis has already gotten some backstage heat. James Caldwell reports that, according to sources, a lot of people were turned off as to how she carried herself as though she was already a big star.
He also reports that the Knockouts made it collectively known that they wouldn't want to work with her if TNA does end up signing her. According to Caldwell's source, "I've never seen a guy or a girl rub the locker room this much the wrong way."
Everything I've managed to find online about Isis inside the ring over the course of this week says that she's absolutely awful inside the ring. I haven't seen her work or anything but her being shit in the ring is just the overall first impression that I get.
