Well, as a mom of a flyer on panthers who's had her kid sustain 3 concussions since the week before Halloween, and is probably out the whole season..I'll say worry about your own problmes because clearly from judging by your Facebook... Cheer shouldn't even be close to one of them.
Seriously if there are last minute injuries, crossovers can be necessary. Or even of the utmost importance. And when you get to the point where they can't be used anymore due to bid techinicalities. People who have zero first hand knowledge should really just STFU and not spread rumors.
