but let's be honest, would the exact same roster look as good now with Byron or another coach at the helm?

Luke Walton deserves major props for getting everyone to buy into the team first (Randle and Young are the obvious early beneficiaries).

Some have written articles on this already but I don't think it can be overstated... the fact that Walton invites the players to challenge his decisions means they have more investment and agency with the *team's* success. Contrast that with Byron's "my way or the highway" coaching style and it's a completely different environment.
