Lauri played 40 minutes. He was asked to guard KD 1:1 most of those minutes. And then, because this team doesn't have/play a 5, he (as everyone else) was asked to help into the paint. That didn't end up so well, but who on this team could've guarded KD better 1:1? No-one.
Sure, he didn't get rebounds. That's a bit tough when on pretty much every play he's guarding KD (or sometimes Booker) outside or mid-range. Still, the Suns had a total of 5 O-rebs the whole game.
On offense he was passed the ball a total of 16 times. And with those he had 12 FGA and went to the line 6 times. He might've not had an offensive possession where he touched the ball and *didn't* try to score. Sure, KD was draped on him. But 21 points on 16 passes received is beyond efficient.
Yeah, the final play wasn't good. I don't get the design, but neither did Lauri execute it well. Doesn't really matter though as the Jazz win probability at that point was something like <0,1 % - the game was already lost.
Can't really fault the Jazz offense on a night they score 128, shooting ~45 % from 3, getting to the line 31 times, 27 assists etc. etc.
But this was not at all Lauri playing badly. The team chose not to play the ball to him, like, at all. Scoring 21 in a game like that is amazing.
