I think he was for 4 of them. I watched that game and was impressed with how he forced Booker to shoot contested fadeaways. Which he missed for a while and then he finally made a couple of them (he’s averaging 30 ppg - so he’s going to make some). I unofficially had it as Booker shooting 3-7 head-to-head watching the game - not counting the last one coming when he was the primary defender and Vassell flew out late to help when Steph was late getting around the screen.
I guess there’s a nuance as to whether you technically scored “on” someone if you used a screen to get an advantage. That might make that 1-6 closer to accurate if a screen negated the attempt. But if that stat is legit, you have to use the same standard on misses and makes (ie if Steph fought over a screen and had a good contest, that shouldn’t be a miss head-to-head if you wouldn’t have counted it if it went in).
Yeah, I'm not sure how they are counting who is the primary during the shot. I mean, to get 1-6 you have to count two makes on Wemby, and Wemby is playing more of a drop than a switch/hedge so I'm not sure why you would put that on Wemby. And both times Castle does fight through for a decent contest. That said, with Wemby's length he might actually still be the closest defender during the shot (which IMO is a bad way to judge who the defender is).
