The way I see it, Boston had the more talented team.
But Golden State clearly had more experience and were battle-tested in these situations, and it clearly showed after Game 3. They also knew how to deliver the kill shots when the opposing team was reeling, which the C's honestly could never do after the Nets series this postseason
Not to take anything away from Golden State at all, but I still believe Boston choked this series away on their own. Sure, GSW played a part in that with their adjustments and improved play, but the turnovers, missed FTs, long scoring droughts, Tatum disappearing. That's more on Boston.
