There's three of them and a million other things to watch. I see it happen at least once a game in every game I watch. After all the aneurysms I read on here over a few times Embiid had it happen a few years back, I notice it more.On that first interference, I am wondering if that is just something the refs aren't looking for, and they're looking at the rebounders instead. I remember a couple other instances where a player knocked a ball out from the hoop and the refs didn't notice. Maybe it's like Woodbury on the tips, they just don't have good coverage of something like that.
