It may sound like a small detail, but the ability to take the time during a time-out to decide exactly what play you want to run for which player while designating an inbounds passer is actually kind of a big deal.
In my experience with the old inbounds play mechanic, my star would be inbounding the ball 40% of the time and I'd have to repeatedly tap the D-pad so I could select my play as quick as possible. Having no real time to decide on an adequate play, I'd often select one at random and then just break out of it once I realized it wasn't going to run its course before five seconds expired.
The ability to plan something out beforehand for the player I specifically want handling the ball is a great addition. I wonder if the play being drawn up can only be an inbounds play, or if we can draw up the next "set" to be run the minute the ball is inbounded. Either way, I approve.
