Sloppy is a bit harsh. He probably went where he felt he needed to go to see between the players, which is rarely a bad option. As to being off the sideline, he's not 2-3 steps onto the court. His heels aren't on the sideline. That's not horrible, especially since there isn't a great deal of room between the boundary and the bench.


They all weren't competitive but that doesn't mean he wouldn't notice his side of the court was getting rather crowded. If that's me, I know I would've been thinking, "L come over...L come over." He may even have moved up in anticipation of the L coming over - thus making him the new T. There's a lot of stuff going on his 1/3 of the world. Not to say the call shouldn't have been made but it's not as though the second screen was the only thing on his mind.

Positioning, whether it was great or not isn't why he missed this play. No matter how good of a position you get, you can't get the call if you aren't looking at the right area in time. He seemed to be watching the previous action...a screen for cutter and the defender that was trying to keep up with him (a legitimate thing to be watching) and he turned is head to the play of interest just as the screen was happening....too late to know how the contact developed. This is even more a reason for the L to have come across as there ended up being more than 1 matchup for C to look at.

He steps up and on to the court and turns at an angle, creating tunnel vision, to look back down into the paint at 3 defenders doing nothing. If he stays flat to the sideline and FTLE extended he maintains a wide open view. A1/B1 would come into his left peripheral and he would be looking right at A2 and see his potential screen.
