This might be better than her staying. Her best friend on the team got tossed and while it's just speculation it might be that Cooper was lured into the fight. Was it just a coincidence that a team member was ready to record the incident? And if so DeShields might not have the fondest of thoughts about that team mate. The upcoming year would be a nightmare as far as team chemistry, especially with 4 freshmen there.
IMO, despite her elite skills and athleticism, she was a moody diva that needed the ball in her hands to be effective. Russell would have been a much more damaging loss. The team can now circle the wagons and Holly can instill an "us against the world" mentality.
