I disagree. Huerter isn’t a good defender either. While Monk’s is no stalwart, he seemingly makes more plays on that end of the floor including the occasional highlight reel block.
Also, while you’re right that Monk can get into trouble playmaking, he is far better at it (especially PnR with Domas) than Huerter and simply can bring more to the table on both ends when his shot isn’t falling.
Circling back to offense, Monk has shown the ability to score in a multitude of ways that Kevin cannot. That's precisely why MM is capable of scoring outburst such as the historic Clippers game last season, as well as many others like it. Kevin rarely ever hits 30 points in a game no matter how hot he is because he can't create his own shot or get to the cup like MM.
Aside from Swipa, one could argue that MM not only makes the most concerted effort to get to the rim but also is the teams most multi-faceted scorer (including 3's that Domas doesn't usually take). So even when his perimeter shot isn't falling, he can still take it to the hoop.
Kevin might be the better player off the ball wrt to movement and cutting, but it doesn't result in more scoring than Malik produces on other ways. Yes, I know Huerter averaged more points last season, but he also plays starters minutes and takes more shots.
