The solution would have been to have KBD guard Adams and having Jakob guard Anderson/JJJ/Clarke. Of course then you have a hard time on the boards.
Anyway, Murray's never been a shut-down guy. Literally never. It's not his thing, and that's not where his defensive effectiveness comes from. The Spurs don't have a one-on-one guard defender. These are things that have been known, but I guess folks wanted to believe it would be some back-and-forth duel. Those are the kinds of expectations for Murray that will lead to him disappointing people -- at least right now. He's not a great one-on-one scorer or defender. To this point, he's not a good bet to win that way. He's a much better bet to have a great all-around game while other guys play well enough to blunt the difference. Despite how much Morant scored, the Spurs had chances to win the game. That's probably where Murray and the Spurs should focus rather than DJM thinking he needs to match Ja himself.
