Spurs match up well but if you look at the rosters one thing is clear: How far we go depends on the imrovement of Murray/White/Walker.
Neither the Fakers nor the Flippers have a strong guard rotation. Beverly/Williams is ok but nothing to be afraid of. If Murray and White take a leap they might even outplay them. They can guard both and Murray has a size advantage on Beverly. Rondo/Green is even worse. LA will cancel out AD. Spurs got Morris, Carroll and Gay to throw at #2, Paul George and LeBron. DeRozan even played well against PG13 when he was in OKC. We also got good help defenders and our bench is better than all 3 of those teams benches. Against the Clippers LaMarcus would destroy Zubac. Harrell is a hustle big, but no major offensive weapon either.
Against Golden State White and Murray would lock down Steph/DLo/Klay. Morris would probably fight Draymond at some point and LA can't be stopped with that many shooters on the floor. I also don't see Klay ever stopping DeRozan.
I think this Spurs team is so versatile that it can create a lot of match up problems but adjust to almost any look on defense
