Before Wiggins was traded to the Warriors, he was already inconsistent. In fact, the Warriors were the best team for him since he was able to win a championship there. But now that he's with the Miami Heat, it's a different culture, so he might be influenced to play more consistently. Though honestly, I don’t expect much from him, but hopefully, Coach Spo can unlock his consistency.
Hopefully, he goes back to his former by being in the Heat. Coach Spo is different and I agree with you that he can unlock that inconsistency and probably lack of confidence.
There is more with Heat but we always see them do good every season and they're consistent with that.
