I don't know any of your DKs, so this isn't directed at any one in particular. Just giving my 2-cents to this topic:
I have seen several of these ODP tryouts, and there are LOTS of kids that look like great players. The problem is that there are TOO many for the pool, so tough decisions have to be made.
I think when you have a group of so many talented players who are all trying out for limited spots, it is CRITICAL for a player to do something that "stands out" from the others so that he/she becomes a memorable player. If the coaches don't remember your DK enough to give an accurate evaluation, she might not have stood out from the croud of other very good players. This doesn't mean that your DD isn't an awesome player, but maybe she didn't show her stuff in a memorable way THAT DAY, or over the course of that tryout. Or maybe there are two players with equivalent skills but one is just a second or two faster, or stronger than your DK. It may be a seemingly "little" thing, but it may have been enough to tip the scale in favor of one or the other.
There are so many aspects that can and should be taken into account when trying to NARROW the pool of extremely good players. I would say that many CPS are oblivious to many of these skills/traits/characteristics when watching a soccer game. How good is the player's FIRST touch when receiving a pass? Does the player demonstrate confidence with the ball or are they too quick to dish the ball? Speed is important, but not if good ball control is missing and they can't keep the ball in 1v1 or 1v2 situations. Is the player REALLY good at one position or can she play other positions as needed? Does the player BOOT the ball or does she make accurate LONG passes TO HER TEAMATE? Is the player coachable? Does player have good attitude on and off the field?
When you are watching your DKs play this weekend, pay attention to these "little things" ... do your DKs have room to improve? I know mine does...that's what practice is for!
