To be honest, when Fournier plays like this I don't think we're going to miss much by losing Brown, at least in the starting lineup. Similarly skilled offensive players, but Fournier seems to be the better playmaker for others - similar to what Gordy brought last year. And defensively, Jaylen is the better individual defender, but Fournier seems to be a better overall team defender (which JB really struggled with) and solid all around defender.
Losing Fournier's presence off the bench is what will really hurt.
