You are totally correct indeed, but I'd like to point out a few things...
We do tend to say that every single season when we lose great players. How will we "replace" Stef and Bria? KML and Stokes? Tuck, Jefferson, and Stewart? The answer is that we don't ever really "replace" them, but rather add new dimensions to the team for the following season.
What Gabby and Kia do for the team cannot be overstated. But it's clear that in big games, while Geno has finally come to trust Megan a bit more, we really still only go 6.5 deep. But next year our genetics will be different. Maybe worse, maybe better. Z WILL improve over the summer and will be a starter. Meg WILL improve over the summer and either she will start or Christyn will. We will have a healthy ONO, Mikayla and Batouly on the bench so that means that Geno will have the ability to go a legit 9 deep.
When we had Stokes, we had a huge goalie/shot blocker on defense. When she left, the team had to learn to excel at help defense. Right now they are VERY good at it. IF Z can learn to keep her arms straight up and not "jump" into offensive players taking shots, SHE Can be that defensive stopper as well. That means not only will our help defense be great, but also we will have a skilled shot blocker to mop up any mistakes. We don't have that now.
My overall point is that we can't replace any great players who leave, but the best thing about freshmen is that they become sophomores. Lou, Gabby, Crystal, Z, Megan and Batouly will ALL improve next season. I hope Mikayla gets healthy soon because I think she has the ability to be part of the core group as well.
The future's so bright, we gotta wear shades!!
