DK has taken over and now coaches the 21 Blue girls. As for 10 leaving, I reached out to find out this info rather than listen to BS on the site and believe it. What I was told (which matches up with how the fall/winter actually went), is that 4 girls left, after tryouts the Blue team had 18 girls and Red had 22. They left spots on Blue in case they decided to move people up. 3 girls who were unhappy from another club came and tried out late and made Blue. So there was no 10 girl turnaround. 4 left, 3 new came on and now Dave is coaching. I think 21 Blue will do just fine.
Nobody would ever dispute that DK is a master salesman!
It's very simple, if you made the team after tryouts you have the roster that was emailed to each blue player back in September and you can compare it to the current team. To say they held spots in case they wanted to pull up red players is just BS! If they had red players good enough after tryouts they should have been offered a spot like everyone else.
Sounds like you are happy so far and I hope it works out for you.
