This is a nice breakdown.Exactly. I’ve been preaching this here for two decades which is why we will continue seeing Tatum ISO’s unless there is a rule change. To reach your goal of scoring on the possession you first need to accomplish several objectives.
Objective #1 - Don’t turn the ball over.
Objective #2 - Get off A shot....at the desired time on shot/game clock based on game situation.
Objective #3 - Get off a quality/clean look shot by your best scorer....at the desired time, etc.
Running a set in final possession against final possession defensive pressure makes accomplishing all 3 of these objectives very rare.....especially the timing which depending on game situation may be most crucial.
At the end of the day, Tatum in iso or P&R is our best percentage chance of getting points against last-possession defense most of the time. This will be even more true once he gets better at getting calls. This is not going away.
The only time that this is unlikely to be the case is the rare occasion where the defense has a guy that can legit defend him, and there are few (Kawhi, Durant, Butler, etc.). In those cases, we may start seeing more of Brown breaking down his guy in the future. Maybe.
