Engine error imo.  Happens all the time.  My guess is that that the pbp notation occured after you gained possesion (just checked and confirmed).  I'm guessing it's a logic issue.  Since you weren't in the spread when the rebound occured and possession starts, the sim continues in the former set (non-spread set) until possession is complete and you will go into the spread once you get the ball again.  I've noticed that for years.  Going to spread occurs earlier irl.  Perhaps they could give us the choice like they do on 3-point frequency and tempo late in games...

Good points red on the 4 second minimum to get a shot.  Magically at five you can shoot lay-ups.

Another logic error is the fact that clock runs in first half under a minute.  So any basket made under 5 secs usually runs out the clock at the end of the half or at the very least maybe an inbound pass.
