I think you need to give them a day to cool off and think about it. Maybe right after a terrible shooting night they were hot headed going in. Give them the benefit of the doubt and talk again in a day or two about it. Maybe one on one so they can feel not ganged up on right after a tough night.
Cooler heads prevail maybe? But if they still feel the same way the next day, sounds like the team is splintered for good.
A team can’t win long term without playing defense anyway so find another team and take your passion there.
Best of luck.
